Everything is mostly working great with the pro2pdf merge, however, in certain instances if a user does not input anything the final pdf has strange characters showing. It looks like this: a:1:{i:0;i:356} . Any insight you can offer would be greatly appreciated.
It appears the fields showing the ‘strange characters’ have the PRO2PDF format dropdown set to a “Repeatable” or “Image” option. We would likely need to see the field map layout and the resulting PDF to determine exactly what is causing the issue.
