Describe the bug
I have created a new network but when I go to the players tab I cant set other players to network users.

To Reproduce
Forge 1.12.2 version 2855
SpongeForge version 7.3.0
Dashcore MSMP modpack

Expected behavior
All users will be blocked access and it's impossible to change that.

Screenshots

The possible cause is data corruption or your UUID has changed. If you have OP permission, you can enable super admin to change the access level of network members, or transfer ownership to you.
