Thanks for the additional information.
In 22.12, we fixed bug related to this Add Cluster command, so I am really interested to know how to reproduce such issue, as I thought this annoyance was really fixed in 22.12.
I am wondering, if you had not used 22.05 (or older) when you tried to Add a cluster? That would explain why you can not reproduce this issue with 22.12.
If not, we will try to find how this could be possible.

For the "Delete", we will look at it soon.
