I get "Der Wert darf nicht Null sein. Parametername: key" when trying to add a single termbase

Good evening here in Europe,

See error stack attached. I get this when trying to add a single FR (France, I think? But they mustn't be locale-sensitive, normally) to ENUK termbase to our FRCH to ENUK project, i.e. doing it one at a time, extra carefully.

This termbase was created using a recent version of MultiTerm. I get this when trying to add other termbases of the same locale, too.
