Hello,
Sorry to hear you are having issues. But, why do you paid again for Start11v2.5? The licenses key for v2 should work for Start11v2.5.
For the revise taskbar tray icons, sorry, perhaps it was overlooked when you posted it on general Beta Feedback thread.
I tested on my system and I can not reproduce your issue on my system.

As a test, try installing on Windows Sandbox and see if the issue still appear while in there. Do that and report back.
