Problem
You accidentally turned on the Require new signature? toggle while filling in the Create Contract form.
Possible cause
The Require new signature? toggle is easy to click by accident. If you notice before saving, you can simply switch it back. If you have already saved, you can edit the contract afterwards.
Solution
If you have not saved yet: Click the toggle to switch it back to off before clicking Create.
If you have already saved: Go to the contract list (Memberships → Contracts), find the contract, and open it for editing. Switch the Require new signature? toggle back to off and save the changes.
If the problem persists, contact support and include details about:
The name of the contract in question.
When the issue occurred.
