Here is a question about licence move to new mac

[HeJ1]

I need to sign out the license on the mac that I used before.
I log out according to the screenshot (refer to the attached picture),
but on the new mac, the software prompts me that the lic number is full, which means that my logout on the original mac is not successful.
Excuse me How do I change it?

my license version: Parallels Desktop 16 for Mac Standard Edition
mac os： big sur 11.7.1
