Strange clients in master realm after update to KC26

Hi,
after updating to KC26, I have strange new clients in my master realm. The names of the new clients are all with the same name scheme “realmName-realm”.
If I create a new realm with the name “Test1” and go back to the master realm->clients, there is a new client named “Test1-realm”.
I can not delete this client, but if I remove the realm “Test1”, the client in disappears.
Is this a expected behavior?
Thanks!

It make sense to have it, so you can configure access and permissions from Master realm users to other realms.

Hi,

it’s also stated in the docs

I found it under 11. Controlling access to the Admin Console->Global Roles.
Thanks!
