Mod requests (orders).

Hello everyone... Is there a mod or a fix that corrects the Sovereign ability for Isabel in the "All Campaigns" mod, or can you tell me how to fix it?

It seems like no one cares. Anyway, in that mod where you wrote the first time, there are no fixes for Isabel and her specialization in training. Either you have another mod for this, or a map with such a mod. Delete everything unnecessary from the mods, data (there may also be mods there), maps, usercampaign (probably) folders and replay. Well, in general, you need to describe the problem in detail.
