If you understand it right, the form is not redirected to PayPal on submission.
What happen is the PayPal field is not required and if the form is submitted with the field not selected, it redirect to the default Thank you page without going to PayPal.
You can fix it by setting the field as required or select hide from the PayPal field itself to make sure it is always checked on submission.
In case you are referring to something different please let us know.
