Migration from Settings --Apps area ...? Beta 3 - 1.5.2

I am trying the beta 3 of 1.5.2 (Plus version). When I go into the settings --Apps dialogue, there are folder icons on the side of each of the storage path locations. These are all greyed out, and when I click on them, they do nothing. Should I be able to initiate a migration from here ? I am running this is a VM in Proxmox VE 9.1.1.
