On the CurseForge site, in the localization section, some phrases for different languages ​​are missing, including Russian.
For example: L.MISC_SETTINGS, L.ENABLE_LFG_EXPORT_BUTTON, L.ENABLE_LFG_EXPORT_BUTTON_DESC, Etc...
I also noticed that the English localization file has 403 lines, while the CurseForge site has 531 phrases.
It seems that translations on the CurseForge site need to be updated.

We just imported the latest loc strings into CurseForge. Can you see if you're now able to access what you were looking for?

Btw ..
The question about the number of phrases remains relevant: I also noticed that the English localization file has 403 lines, while the CurseForge site has 531 phrases.
It seems that there are phrases on the CurseForge site that are no longer in the addon files.

Yes, I see it now.
I also updated some other phrases. If possible, please upload the new translation.
Thanks.

Ah yes, there are probably old localization strings that are no longer relevant. We'll investigate this.

As far as your new translations, CurseForge will auto-pack them into subsequent builds.

Thanks!
