How do I force Channels DVR to rescan my storage?

I watched several recorded shows on my computer while doing some other work by direct play. I than deleted the files from the pc hosting the DVR to free up some room and also as a way to tell what I have watched already (not deleted and I know i didnt watch it). The Channels DVR program and the Channels app both are still showing the deleted shows when I click on them it does “playback failure” or similar. Basically I am stuck with deleted show still showing how can I get rid of that?
