Have you deleted the submissions from your form?
I did check your form and it does not have any submissions. I am not sure what caused this issue but when I recalculated the submission from our backend, it shows 0 submission.
I did send a test submission in your form and it does gets displayed correctly in submission page. Please be noted that we do not delete submission data and whatever submissions you receive will always be in your forms submission page.
