Pdf Expert weirdness

I was typing on a form in PDF Expert yesterday and could not get the cursor lined up where I needed it. It seemed to be specific to this particular form. It’s one I duplicate and use repeatedly for work. This was on the Mac -when I worked on the ipad version, it seemed to do ok. I do not have this issue with other documents. Thoughts?

Difficult to say without seeing the pdf, but I have seen varieties of oddness in the desktop version of this and other pdf editing apps.

Indeed. I was trying to decide if it was worth deleting and re-installing.
