Maybe I havent understood, but I think it is not necessary to push user to add group to Reference list. Most of the references are used as a references. Other groups may be insert as an option. If you force it, it blocks to add references.

Severity: enhancement
The "group" parameter is necessary if you have multiple reference lists, which is uncommon but is used some times. Re-wording to make clearer.

I think this may cause also the following problem:

In the fix for bug 59180 we made the group have a placeholder (default text) that says "General references" (in English), which should discourage this enough – marking as FIXED, though happy to discuss better ways to improve this if you want to re-open (or create a new bug).
