Hi,
I am having the same issue:
While creating a pool (repeated several times), for some unknown reason, a given name (like "POOL") was replaced by "/media/2fe90cb3-a2c4-45d1-83cd-a6ce90421e87" kind. The pool itself is working, but that name makes it confusing when creating shared folders. It would be nice to fix that or to have a workaround.
All software are latest upgrade.
Cheers!
