Sorter disappears

I have three monitors and tried to move the sorter tab to another monitor.

It now shows up on the left side of the left-most monitor but only for a few seconds and only when I press F9 or F10 twice. Moving my mouse over the spot where the sorter tab popped up doesn’t do anything.

I’ve tried quitting the sorter and toggling the sorter options and quitting and restarting the sorter with no luck.
