Deleting Time Casule from Orbi Network

I no longer need the Apple Time Capsule that I was using for Time Machine Back-ups.  I disconnected it from my Network as required.  When I go to the Orbi app, I select the Time Casule in my Device List, then scroll down and hit the red "Delete This Device" button.  The red area goes to a pale red color and just sits there and will not remove the device from the list.
