Perhaps because East Germany, or at that time East Prussia, had a great influence with German settlers in Central Europe. I wouldn't be surprised if this is the case that the results are similar :)

Maybe 1/2 East German and 1/2 Croatian (based on your surname)?
On K13 you have a distance of about 8 from the East German average, and 10 from the Croatian average, so you are balanced between those two with a lean to East German.
*Edit, using the updated Croatian average and the old East German/German average:
Target: LenzhkaCode:Lenzhka,35.2,36.2,7.44,3.82,9.42,2.3,1.24,0.7,1.5,0.52,0.95,0,0.7
Distance: 8.9937% / 8.99368226
71.1 East_German
28.9 Croat
Let's try the overall German average + Croat:
Target: Lenzhka
Distance: 9.7271% / 9.72710344
59.5 Croat
40.5 German
Second one looks okay as a parental split, assuming recombination resulted in you leaning to one parent. But that distance (9.7) is pretty high.
I don't get why everybody talks about Roma when she scores 1% South Asian in K13 and DNAntro breakdown is usually wrong. The true puzzling part is the high east med and low west Asian combination. So the European side must be very low to zero west Asian, this is why in mix mode Finns pop up a lot.
Maybe, but wouldn't that be displayed in the oracle mix mode (Roma, or even Gypsy)? Because, strangely enough, I tend to match Semitic populations there.
I shared 2 photos of my great-grandma in another post because (according to my cousin) she looks similar to the Ashkenazi phenotype. Maybe there's a connection?
