Can not use plugin pot

Hi!

We’re using loco pro and are having a problem with translating the plugin “WeePie Cookie Allow”.

When trying to translate it, loco lists four different files (2xpot, 2xmo) where we only want to translate one of them (the official one provided by the plugin, which is /lang/wpca.pot)

Trying to setup an additional language, it always only takes 5 strings from any source (not from the correct pot file).
In advanced configuration, I set the template path to wpca.pot in various versions (starting the path from wordpress root, from wp-content/plugins and from this pulgins folder).
Also added it to the field below – no success.

Could you pls tell me on how to add this specific pot file so I can translate it?
Because when I open the specific file in editor, I can’t use auto translate as this is only available when I create a language first.

Thanks
