Mod's strings became 'not found' after repacking

[theillusiveboy]

Hi, I'm fist time trying to edit some mods for me, so I installed the mod, got the some items from mod in game, closed game and unpacked .pak file with Baldur's Gate 3 Modder's Multitool

I didn't change anything in unpacked folder, packed it again the same way in BGMM, installed new version of mod (technically new, because again i didn't change anything), loaded my save, all items are still working fine, but every string (like name, description, etc) became "Not found"

I tried to google it in many ways but didn't find a proper solution or things I did wrong, so i'm asking for help
