I can see that you have matched 5 fields. There is no limit of the fields that can be added/matched. Thank you

Can you please confirm that you are having problems adding new fields and saving the changes? Yes

If this is the case, please try removing the integration and adding it again as you might need to reauthenticate to Infusionsoft in order to make changes. I tried this already

Is this followup from this thread - https://www.jotform.com/answers/1440366?

If your issue is not resoled, please reply on that thread to avoid possible confusion.
