TI 2013 Completes Task But Does Not Recognize That It Is Completed

I have three scheduled backups in TI 2013, latest build.

Two seem to be working fine (one disk backup and one file backup).

One of the tasks, a file backup that backs up everything on my data disk, appears to execute the scheduled task. I can tell this by seeing the incremental files on the backup disk. However, the TI interface indicates that no backup has been made and shows no recover button for that task. The task was obviously competed at the scheduled time, but no recognition that it was completed.

Is there a solution for this problem? Right now there is one full backuo and one increment.
