Ok sorry for the confusion, I'll try to explain what is going on the best I can.
I have 2 tabs pined, Inbox and and the main Library (all tabs in Album Covers view) no other tabs open.
Now i add a new tab, in the left slide bar i go directly to the same folder I have musicBee Monitoring and open it in the tab.
I browse around this tab clicking tracks.
MusicBee scans and moves the track I clicked last to the main folder that is monitored by MusicBee.
It does this randomly.
The folder being monitored is full of other folders with music files.
