What worked for us was:
1. Editing the forms in our web browser(not editing them offline in adobe).
2. After entering all the information and validation of the data(in the form open in the browser),then saving the form to the desktop(offline).
3. rechecking in adobe that the form is correct and then uploading it- if there is an error, repeat from step 1.
unfortunately we couldn’t offline edit the forms in adobe and have a validated form, so we edited in our web browser.
I hope this helps.
