With a signature card 2.0 test card connected, I saw a wrong display of the private key location in the key details.

It was first shown as "on this computer" and after a second changed to "On this computer and on smartcard".
But the key has never been on the computer, it was issued on the card.

After that it was usually only "On this computer and on smartcard" except when I opened a details view for another of this cards certificates:

Opening yet another detail shows that always the last opened detail shows "On this computer and on smartcard", the last one before that then changes to "on this computer":

It does not change back again on the previous one when I close the last window.

The contents of the key file for the middle key:

Token: 89490171500022806460 NKS-NKS3.4531 - 8949017150002280646

The others look basically the same.
