On the Details page of any device I can not see/change some fields. Class, Status, Environment, all of them have values on the database (system table) but those values are not shown, and can't be changed since the drop down menu appears enpty. Still the groups lists show the correct devices listed on them.
I'm running a fresh install of 2.2.2.
Upgrading to ver. 2.2.3 fixed this issue for me.
This is a bug that has been fixed for 2.2.3, which is available now.
