Save (to) new version not working?

Hello,
saving new version isn’t working as it was before.
Everytime I invoke the shortcut
(shift s in my case) it ries to save it as xxxx-01. So the number is not advancing like it did before.
Or have I missed some changes? This is Dorico Pro 5.1.80 on Win 10, I checked the release notes, could not find anything mentioned.
Maybe a bug?

Cheers R
