PDF text merges 2 pages of text - Why & how to stop it? (pics attached)

[Rachel28244341yhwe]

I am trying to put together a client's chart so I cannot share much, but I've attached a screanshot of a deidentified section to show what's happening. 

I'm in the trial phase of Acrobat Pro. I combined 141 pages and overlaps began when I edited font and then saved. multiple pages in the document merged to place the text overlapping. I can't effectivly edit it out so I tried to download one note at a time to sent (3ish pages), I edited the font again (just making it all the same size) and it did it again! So it's not the large file size that's causing it. How do I fix this?

Editing text in a PDF is always a 'dangerous' endeavor.  Although Adobe has built-in text editing tools and capabilities, the very nature of a PDF, and the various ways a PDF is created make text editing success a variable, not a certainty.  All PDFs are different, and two that look identical may in fact be constructed entirely differently under the skin, and their editability will vary.  It may not be possible in your situation and workflow, but it's always preferable to make edits in the source documents, not the PDF - but I know this isn't always possible.  Not a solution for you, but a reality in some cases with PDF technology.

My best,

Dave
