Content Update Restriction not saved

Every time I open the editor the "Update Restriction" option of a number of groups is reset to "Can change" even though I had set it to "Cannot change" before. I think this is happening for groups that were not already set to "Cannot change" before updating to 1.6.0. Cleaning the cache and rebuilding the bundles does not help.

 

Are you saving the project before you close Unity? I've noticed a lot of addressable settings don't get saved automatically and I have to manually save the project for them to get written to disc (I noticed this because git wasn't picking up my changes).

 

I tried that but the changes are still forgotten after restarting the editor. I tried with and without rebuilding the bundles (clean => build => save).

 

i have same problem. did resolved this?
