Acrobat - missing text when combining PDFs

[Claire220215689c1k]

Hi, when combining PDFs, text on some pages diappears. Sometimes it's whole words, and sometimes it's random letters. I have the most up to date version of Acrobat (64 bit). Why is this happening? How can it be prevented and is there a workaround?

Thank you

Is this text a part of a text form field? If so, you need to make sure the files are flattened before merging them, or that the fields in each file have a unique name.
