License set back to starter

[dakota127]

I currently had 3 out of 5 licenses activated (für my 3 Pi musicservers).
I recently set up a new Pi OS on a new micro sd card on a spare Pi 3 to be later put in my existing pi musicserver number one. I deactivated the license on my running musicserver and activated the license on minimserver running on my spare pi. After I checked everything I put the new micro sd card into my existing Pi musicserver. As a result, the license was reset to starter. Now I still have 3 out of 5 activated, but im running only 2 musicservers.
Now here is my question: does swapping a micro sd card into another pi reset the license and why? And please reset one of my 3 licences.
