Some of the submissions are missing.

Hello. A few days ago we discovered that all but 14 submissions in our "Restaurant Sign-Up" folder are no longer there and we aren't sure what happened to them. Is there any way to tell what happened and how to recover them? Are they backed-up somewhere?

I can see 242 submissions to the form 81041153984152. Could you please share the ID of the submissions which are missing so we can check?
