Libreoffice on multiple monitors (Win 10). Menus open on wrong monitor

Not tech minded. Win 10 on Dell Inspiron 7506 2 in 1. LO (x64). I use 1 or 2 monitors in addition to my laptop. Don’t know tech terms but all LO app ‘File’ ‘‘Edit’ ‘View’’ etc sub menu boxes such as ‘‘Properties’’ and ‘‘Format’’ open on wrong screen - sorry don’t know how create link to screen shot. This may be similar to solved bug 48168. Not a major problem but irritating and doesn’t happen with other apps.

Please file it as a bug.
