Activating under wrong computer name

I'm having an issue with activating new installs. See the following previous post:

https://community.teamviewer.com/t5/TeamViewer-13/Assignment-failed/m-p/32204#M1143

Now I'm getting the following message:

TeamViewer_Assignment (r350)

Device with ID = ####### with Alias = 'H129-400-1' already assigned, stopping=> Assignment successful !

The issue there is the computer name is actually "H129-400-25", for example.

Any suggestions?
