I noticed a similar issue yesterday. I love 7+ taskbar tweaker, one of the reasons is that I can easily set my own window order which speeds things up for those windows I frequently access because I know right where it is (i.e. Outlook mail always first, Outlook calendar always second, Teams always third, etc.). When I discovered the multiple desktop feature the other day, I noticed that the order changes when I switch between desktops. Screenshot of my version / setting is below.
