Hi Kevin,
Is this issue only affecting one form? Meaning, if you create a new test business process and test form that only has one single line field for example, do you get the same behavior or does that form display fine on the "thank you" page after submission?
Assuming the issue is related to a specific form design, then you may want to contact your Laserfiche Solution Provider to get further assistance. You can use the Laserfiche Forms Support Checklist for a list of information to gather. If your Solution Provider needs further assistance, they can reach out to the Laserfiche Support team.
