Missing parts of print dialogue

Hi -

I have been using MindJet MindManager for years, and quite happily on my current laptop for some months. Recently I have been having trouble with printing - I can't control how many pages the print comes out as.

The print dialogue fields seem to be blank (see image).

It is only MindJet MindManager that is affected, Word and other apps seem to print OK with full control. Has anyone seen this before and can they give me any suggestions?

I have Windows 11, and I have two printers connected (both work fine with other apps, neither work with MindJet, and produce the same result).

Many thanks!
