One Sharespace but two entries on network

I have a Mac and use a sharespace .

I have the Sharespace showing up twice one that is usable and the other unusable and the unusable has a “-backup” tag attached to the name.

What have I done and how do I remove the unusable “shadow drive with the - backup name” ???

Don’t  try. This is the name presented to TimeMachine in case you want to use the Sharespace as a time machine backup device.

To test this, openup timemachine preferences and do a “Select Disk” (but don’t actually select it unless you want to).
