If it's vanilla Enderal, you may be loading the language pack before Enderal, when it should be loaded after. This reminded me, I am going to remove fontconfig.txt from loose files, after that the load order in vanilla won't matter.
If it's a modded game, probably, some mod changing UI interferes, most likely overwriting FontConfig.txt. This means, changing load order on the left side in MO2 should also be enough.
