[Membership 2 Pro] Membership Pro Manual Payments Not Working

I checked on our Manual Payments today, by trying to become a member with our Pay by Check button, and found that the website isn\'t responding correctly. Clicking the button showed the user that they\'d successfully signed up (rather than the instructions on how to pay by check) and automatically made the account a member, even though we don\'t have a payment for that membership. I\'ve granted support access. Thank you.
