Changing server language

Hey everyone, hope you are all safe, i ve tryed to figure this out on my own but I couldnt, so when i open a vendor the item name appears in english but on a Xmog NPC it appears in spanish(wtf) also the chat names are in spanish like general chat etc are all writen in spanish, how can I change this? i have searched and didnt find anything about this issue

Thanks in advance!

Ahh by the way 3.3.5a branch

it depends on client language on clean core.

When my friends log in the same thing happens and with that client if i join another server its all in english so im pretty sure its about the source or some config that i really cant find

a clean trinitycore have a lot of things multilanguage, other servers may have deleted other languages. like i told you it depends on client language.

Im gonna take a closer look to that, many thanks!
