Error: Deployment at address 0x85ba1219df574a97B3a329b1653B61EE496c14a7 is not registered

I am trying to upgrade a freshly deployed and upgradeable (Initializable) contract and always get the error

Error: Deployment at address 0x85ba1219df574a97B3a329b1653B61EE496c14a7 is not registered

I don't know even, where this address is retrieved from. It might be from an earlier deployment.
How can I fix that and upgrade my contract?

In the .openzeppelin file the correct proxy and implementation are written.

Hello @Homer

This looks like an upgrade plugin error. Can you confirm how you deployed the proxy and how you are trying to upgrade it?

Hi @Amxx ,

Thanks for your answer. Meanwhile, I can do upgrades again.
I noticed that there is a difference whether I truffle compile --all or delete the build directory prior
truffle compile --all. The first case leads to "Replacing , the latter to "Deploying for upgrades. Maybe that lead to the error.
