Organize Pages feature is selecting extra pages when trying to split a document

Greetings,

(Posting as a company SysAdmin)

One of my users is experiencing an odd issue while trying to export specific pages from larger PDF documents. She scans in documents related to POs and for reconciliation purposes, she needs to pick out certain pages for proof of delivery and authorization for payment. She has been operating in this manner for some time with no issues until recently.

The issue now, is that when she opens the PDF, and selects the pages she needs, Acrobat ends up selecting additional pages that she doesn't need. In most cases, it usually adds the page before the first one she needs, but sometimes it will select a page farther up or down the document. This is causing her to have to scan through the whole document after selecting what she needs to ensure that nothing extra was selected. While this doesn't sound like a "huge" issue, considering that this is a large percentage of her daily duties, this takes up a collective added amount of time.

I've already tried the usual steps including a reinstall, but I've not been able to figure this one out.

Absolute worst case scenario, I can reimage the computer, but we're trying to avoid as much down time as possible.

If anyone has any clues on where to check, I'd greatly appreciate it.
