GedMatch Albanian and jews???? how it's possible?

[Moonlight01]

Hello everyone. it's the first time I post here and I hope to receive useful information, I saw that you are really very experienced and informed, congratulations
Having said that, I wanted to share my results with you, and I hope to clarify my doubts.
Basically, I'm 100% Italian, my parents are from Puglia, but my grandfather was Tuscan.

This is the result with Eurogenes k13 (oracle)

# Population (source) Distance
1 Italian_Abruzzo 3.66
2 Western_Sicily 4.1
3 Sicilian_oriental 4.34
4 Central_Greek 4.73
5 South_Italian 4.92
6 Ashkenazi 7.27
7 Greek_Thessaly 9.11
8 Tuscan 9.56
9 Sephardic_Jewish 9.82
10 Italian_Hebrew 9.93
11 Algerian_Jew 11.1
12 Tunisian_Hebrew 14.19
13 Jew_Libyan 14.88
14 Northern_Italian 16.01
15 Bulgarian 17.32
16 Cyprian 17.73
17 Romanian 19.01
18 Lebanese_Muslim 20.74
19 Turkish 21.5
20 Syrian 21.94

Being in southern Italy, I understand that my Greek and Balkan DNA comes from there, while I don't understand why it appears very strong the Jewish DNA, I have absolutely no Jewish ancestors, even though I know that in the city where I was born, in the past, many lived here Ashkenazi Jews, so maybe that's the explanation, but I'm not sure. Another really strange thing that I don't understand is why Sicily appears very strong, I'm 100% sure I don't have Sicilian ancestors, so this is really strange. I don't even explain Romania, I don't connect it to anything in my family, while another strange thing is that more Jewish DNA is reported than Tuscan, while my grandfather is Tuscan so the percentage should be higher.
Another strange thing I've noticed is that many Italians come out with Tuscany, as if it were standard and it comes out to everyone, how is that possible? I have seen at least 9 out of 10 people have this result with no tuscan origin.

That said, this is the result with MDLP K16

# Population (source) Distance
1 Sicilian (Sicily) 3.83
2 Italian (South Italy) 4.09
3 Italian (Abruzzo) 4.7
4 Greek (Athens) 5.48
5 Greek (Greece) 5.87
6 Greek (Peloponnese) 6.02
7 Maltese (Malta) 6.17
8 Albanian (Albania) 6.28
9 Greek (Thessaloniki) 6.36
10 Jewish (Ashkenazi) 6.77
11 Jewish (Ashkenazi) 6.79
12 Italian (Tuscany) 7.39
13 Greek (Macedonia) 7.62
14 Greek (Greece) 7.85
15 Kosovo (Kosovo) 8.21
16 Jew (Bulgaria) 8.77
17 Jewish (Italian) 8.91
18 Jewish (Ashkenazi) 9.11
19 Jew (Belmonte) 9.2
20 Italian (Northern Italy) 9.75

Can someone explain to me how these percentages are calculated? I don't understand what they indicate, however here I am instead linked to the Albanians of Kosovo, while MyHeritage (the site with which I carried out the DNA test) did not report it to me, he didn't even report me about Tuscany, but he did report me about Sardinia with which I can't find any connection).
In your opinion, from these percentages that I haven't quite understood, how much percentage should I be Tuscan, Kosovo Albanian and Jewish?
Thank you so much to anyone willing to help me

If one gets 0.0 the you are the closest you can be to that sampeld group, this is not procentages, so you are say closest to anbruzzo italians and next group is south italians and so on

Sei vicino a ebrei geneticamente perche l'etnogenesi di Italiani del Sud era quasi similare che a gli ebrei, un misto di Italico, Greco Anatoliano e Levantino. Albanesi sono similari geneticamente perche ADN autoctono degli Balcani è molto similare che a gli Italiani. La maggioranza de la acsendenza di Albanesi è Balcanico autoctono. Gli popopoli piu come gli Italiani geneticamente sono Greci, Maltesi, Iberici, Albanesi ed Ebrei.

What results did you got on MH?
Don't take these results literally, especially this calculator MDLP K16 i got as first two Italian places but i'm not Italian. Got 5 Italian places i have nothing with Italians.
K13 is the best and maybe you do have some Jewish ancestry. BUT
You must compare it with average Italian gedmatch. If the rest of them are same as yours then it does not have to mean you have jews in your family.
