Contact identified by filling out a form. But no record of form being filled out by him

Your software
My Mautic version is: 2.15 (I think)
My PHP version is: 7.0.33

Your problem
My problem is: We have a contact that, according to Mautic the contact was “identified by Quick Pop-up Form”, a Mautic-built contact form on our site. There are also records of page hits, accessed from IP, and Contact identified by source. However, when we look at that form, there is no record of this person having filled out the form. Are we missing something?

These errors are showing in the log: No errors

Steps I have tried to fix the problem: Just starting to research this issue.

This should fixed it
