Adobe Acrobat DC Standard - Blank boxes in place of fonts when combining multiple files
We're using Adobe Acrobat DC Standard on a relatively new Windows 10 machine to combine multiple files. This includes a mix of .doc, .xls, and .pdf files.
After the files are combined and the newly created doc opens up, we noticed that a certain sections of the combined PDF seems to have blank white boxes in place of the actual character fonts. We checked the original file, and it doesn't seem to have these boxes when it is opened on its own. It's only after combining multiple files together that we see these boxes in the final output version of the file.
I thought maybe it was missing font, but that didn't make sense to me since if you open the file solo, the text has no issues displaying, so if it was part of a combined file, why would it be missing the fonts.
I looked online, and tried steps to embed the fonts and such, but can't verify if I did the process right. I even un-installed and re-installed the application.
Any ideas on what could be causing this and how to fix it?
