Included disks in share

I just recently upgraded one of my unRaid servers to 6.0 and came across something today which I do not understand.

When I create a new user share (or try to edit one of my existing ones) I cannot type "disk1, disk3, etc" in the Included Disks field.

Instead I get a dropdown menu with only a "close" option.

Same thing happens if I select the Excluded Disks dropdown.

Is this due to my existing disks still using ReiserFS or is something else going on?

Thanks!

Edit: Turns out I had to re-save the global user share settings.
