Good catch!
It is definitely inaccurate for a large Jewish minority to be in Al Majdal at this point in history. Most of the Jews who used to live in Palestine fled during the crusades, as did many Muslims, and under the Mamluks coastal Palestine has been completely rebuilt. Al Majdal (Majdal Asqalan) was a town built by the Mamluk sultan Baybars (who defeated both the 7th crusade and the Mongols) after he destroyed the port city of Ascalon. It was build 3km inland in purpose so that it won't be a trader port anymore, as part of a wider Mamluk policy to destroy Palestine's port cities to prevent them from being a foothold for the crusaders. So obviously Majdal had little to no Jews in it, and this is visible in later Ottoman censuses. Caesarea, Apollonia and Acre suffered the same fate, but Gaza and Jaffa did not. This should be reflected in the game by only Gaza and Jaffa having port buildings, btw.
Gaza should be the only location in Palestine in which there is a significant Jewish minority particularly because we know that the Mamluks allowed the Jews who fled from the crusaders centuries prior to resettle in Gaza specifically. This heavily implies that there weren't many Jews in the rest of Palestine (except for Jerusalem and Safed). Gaza, as opposed to all other coast-adjacent towns in Palestine at this period, is the only town that we know for certain thanks to reports by traders to have had a large Jewish community and also to have been big and prosperous in general at this period.
Tiberias, by the way, used to have a big Jewish minority but it was razed to the ground by Khwarezmian mercenaries and was only rebuilt in the 1500s. Many Jews arrived to it and other towns in Palestine in the 1500s after having been expelled from Iberia.
On the same note, I dislike having purple as the color for Judaism in game, it is way too close to the color of Miaphysites and it makes the Jewish minority in Ethiopia hardly visible. Why not blue? Purple also has no significant meaning in Judaism, as opposed to bright blue/azure. Azure is mentioned in the bible as the color of parts of the tabernacle and the priests' clothes, it is part of some rites and it holds special meaning: it is associated with purity and heaven.
