Jotform won't allow the creation of new fields.

Hello,

Jot form does not allow me to create new fields in a form that has salesforce integration. 

Previously, I could add new fields and match them to existing fields in a salesforce lead. (See attached screen capture)

But I can no longer do this. Is this a technical error? Could this be related to the new 5 form maximum on new accounts?

Thank you in advance for your help.

Try completing the "Other Information" field or removing it first.  After doing so, the option to add a new field should appear once again.
