Unable to delete image from TI 14

Hi:
After Windows update stalled I recovered an TrueImage 14 image from 2 days before. In trying to clean up I right-clicked one of several images in TI , but nothing happened. I then deleted the image from Windows Explorer and went back to TI but right clicking the image still does nothing. A green line moves across the bottom bar of the image and “time left.” indicates calculating.

How can I remove image this from TI?

Thank you.
