We are receiving fillable pdfs in which only the highlighted, filled fields are appearing, but none of the form formatting (questions, lines, etc.) appears. So, just a blank page, with field data, and nothing else. What is going on?
It hard to say without seeing a sample. If the underlying page is from a scan, it could be that the "Edit > Preferences > Page Display > Show Large Images" preference is unselected. If that's not it, can you post a sample?
