Feedback module stopped showing past data

Hi,

We configured the Feedback module and begun using it starting from March, and yesterday after playing with settings, I noticed that all past data are not accessible anymore. When I open the Feedback page, I see a message:

"There is no data for the period you have selected.
Next survey is scheduled for Wednesday, 14 April, 15:00."

But where is the data for 3 weeks of using this module?

P.S. Our slack space is "fivejars". Let me know if you need anything else to identify the issue and return back our statistics.

Thanks,
