Text moves ALL over PDFs

[DPF85]

This has been an issue for months. I have 4 pages scanned in to a single PDF document, which are part of a medical form I fill out to order medical devices for patients. It has worked fine this way for years. Now starting just a couple months ago, as I scroll back and forth between pages, things I typed in are moving to different areas. For example, the 3rd page has about 7 different bits of info I type in to different areas on the page. I will scroll down to the last page, which only requires a date to be typed in... and all the things I typed in the page before it will literally just pop up. I can sit there on the last page for 10 seconds, without touching anything at all, and watch the text boxes from the separate page just pop up. I have tried just deleting all the random texts one by one within the areas they aren't supposed to be, but then it will delete the text from the area that it *should* be. This is insanely annoying and is costing me far too much time.

I have uninstalled and reinstalled, and my Mac is up to date. Thanks for any advice!

It sounds like your form has become corrupt. Try saving as a new name. If that doesn't work, duplicate the form and save-as-other> Optimized pdf, select Discard User Data- Discard all comments, forms and multimedia (see attached screen shot). This will remove all form fields. Go to Tools> Prepare form> and re-create the form fields. Note, you may be able to copy/paste the form fields from the original pdf, but this may reintroduce the corruption. Also, check for Acrobat updates (under the Help menu).
