Are you able to export a PDF from the plugin’s EXPORT tab?
If yes, then
From the plugin’s SETTINGS tab, select “Limit Field Map to use Dropdown” and click the SAVE button, then from the plugin’s EXPORT tab, select the FORM and reply letting us know how many Field Map Layouts are in the dropdown field are ENABLED (able to be selected).
If no, then
Provide login credentials if possible, using this form so we may check the issue… otherwise if not possible, then…
Use the above linked form to upload a screenshot of the top portion including the settings of the plugin’s ACTIVATED FORMS tab and the EXPORT tab after selecting the Form and Field Map Layout.
We remain at your service.
