conflict with q-Translate, cookie category translations

Hello,
I have to update the cookie settings on this site which uses q-translate for the 2 languages (spanish and gallego). I realize this is an old plugin, but I cannot change it, so am trying to work around the issue, even if that means showing the cookies only in one language (spanish).

So what happened: I insalled GDPR Cookie Consent plugin, and all the categories show up but in english. So I simply translated them to spanish (leaving the slugs in english), and this is what I see now:

On the category list page, I see no option to add translations…

Has this happened to anybody else? Any suggestions on what I could do to show only the spanish? Thank you!
