Form submissions not going through

When someone decides to pay online, the payment will be processed but the form does not get submitted. I have to go into the form and click submissions and then click 'incomplete payments'. From there I instruct each of those submissions to finalize. How can I get my forms to submit after they pay?

I could not replicate the issue at my end.

This is the screenshot of Paypal page, where I am redirected after the submission of form.

If you are still facing the issue let us know the steps to replicate the issue. A screenshot of the values of the form that you are filling in the form that is causing error.
