The settings are changed and the audit function now shows now error (it was flawless working before also, just the checks failed)

The Key-Secret-Pair are checked and identical. A guess might be this:

When adding an installation the key gets associated to a license, but when an installation at https://unacms.com/kands-manage is deleted it gets not disassociated from the license. And then this happens:

Installations (https://unacms.com/kands-manage)

and (https://unacms.com/products-licenses)

As you can see one license is connected correctly. The other two Domain/Key-Value-Pairs do not relate.

Is it possible to make this connection? In the License table I can see only a button with a rubber symbol and I don't want to remove the license.
