That's so strange! That table is a copy/paste of the same values from DEI for all the Athens factions(mac wars and grand campaign, civil war etc), with tweaked RGB values setting the faction colors. that's all it changes, so its a small price to pay to have the units recruitable at all-many of the units have their uniform colors set individually anyway.
looking into it further, I somehow have a different name/key for the succession faction (Athenian Tyrants) but the regular athens factions and civil war ones match-maybe this is causing the units to be unrecruitabale since it is also looking for a faction that doesn't exist. Its possible I copied from both the vanilla tables as well as DEI, colors were the very first thing I worked on months ago.
Sorry for the bug, and thanks for getting to the bottom of it! In short, go ahead and delete that table, and I'll try to get a fully fixed file uploaded in the next day or two
