Move to Another Sheet function


I regularly move completed items to another sheet. The last time I did this the data neither moved, nor remained and now I can't find it. i tried an undo, which wasn't available. i tried to e boot, and I still don't have the information.

i need to find these items or attempt to recreate them and just acknowledge that all of the data saved on those line is gone forever. can anyone suggest a solution and a reason for the issue in the first place? I have been using the product for 5 years and have never has this function fail before.
