There is a chance that your strings files, which are used to handle text in the mod, are mismatched with the mod. This can happen if you extract the patch BSA(s) into your data folder and then update the mod, without re-extracting the new patch BSA(s). Because loose files are given priority, this means you'll be using the old, extracted strings files with the updated mod ESL, and will see text mismatches. You should either not extract this mod's files (my recommendation), or extract the updated version's BSA every time you update.
