I think this is a bug / deficiency of PM+, but perhaps I am missing something obvious.
PM+ build 6784 on Windows 10 Home version 22H2.
In the organizer / browse side panel, the number of photos that match the chosen criterion is shown. Unfortunately the field width for this number is only wide enough to show four digits (and a bit). In my view it needs to be able to comfortably show at least five digits and perhaps six. (And I fully understand that selecting an entry with five digits or more of photos might be a bit much, but I want to be able to properly see that that is the situation.)
