I notice the Steppe in Arabian populations doesn't show up when using Levant_Natufian and Levant_JOR_EBA, but when I utilize Yemenite_Mahra who are supposedly the purest Arabians (correct me if I am wrong) to represent the Arabian component, many other Yemenis, Saudis and Bedouins start showing very low almost negligible amounts of Steppe ancestry like around 1-2%.
The BedouinA was a Levantine Bedouin pop, I just posted them to compare with other Bedouins and Peninsular Arabs.
I then try another run which is replacing the Yemenite_Mahra with Proto_Natufian_(simulated) and ANA_simulated (Ancient_North_African, the African side of Iberomaurusian). I also include IRN_Seh_Gabi_C to improve the fits and here are the results:

Individual samples show even more Steppe among each Peninsular Arab groups. Btw I decided to replace Dinka and Yoruba with older and ancient Negroids such as COG_Kindoki_230BP (West-Central African Bantu Farmer), Kakapel_300BP (Bantu) and Kakapel_900BP (Nilotic Pastoralist) and ETH_4500BP (Mota Hunter Gatherer from Ethiopia) to see if it will affect the Steppe score even a bit.
Yemenis from Amran seem to have the most Steppe both in average and individual levels and Mahras the least (most of the Mahras seem to lack it). Even Saudis and Yemeni Jews have more Steppe than Mahras. Heck, there were two Amran samples who score 6.2-7.2%, one Dhamar sample who is 5.2% and one Yemenite Jew who is 5%, that's Lebanese Christian average level of Steppe (5-7%).
What's funny is how the amount of Yamnaya per individual seems to really varied even among groups such as Yemeni Jews and Amranis, some have around 5% while other individuals have close to zero to literally none.
Btw here are the coordinates for the last model:
