Missing backup definition files in macrium reflect

I have two backup tasks that appear in the "scheduled backups" tab, and they run on schedule, but they don't appear in the "backup definition files" tab.
This happened due to an uninstall and reinstall.
How can I get them back into the "backup definition files" tab?

I still have the reflect folder in my documents, with the xml files that define the backup tasks. But for some reason, that isn't enough to get those tasks to appear in the scheduled backups tab.

Another minor issue: when I boot from the MR recovery partition, in order to run a restore, it doesn't know where to look for my backup files. I have to add the folder manually, and then it forgets again the next time.

here is an answer that works, from shemp at malwaretips. com:
open reflect and click the "Backup definition files" tab.Then click the + ,that should allow you to add the existing xml file you have.
