My Passport appears twice in My Backup

I only have one external disk but 2 entries appear in My Backup.(one connected, one offline).
I re-installed the software, but the problem remains.

I guess these entries are stored in a config. file somewhere but I can’t seem to find it.
Anyone any ideas…

Thank you!

Hi,

Please select the WD My Passport drive which shows as offline and Delete Backup Plan for it.
