Replace authentication key error

[jgordon]

I'm running Linux, Zorin OS 15.1.

In the Configurator, I created a key pair and then saved the public key to a folder.
Later I then altered the access group for the public key and re-exported the public key.
I chose the same name and folder and Veyon Configurator asked me whether I wanted to replace the existing file, I said yes.
I then get an error "Export key, file xxx.pem already exists even though it asked me whether I wanted to replace the exisiting file or not..
