Recently when I edit a PDF the first time, the fonts are fine. It is only after I have saved the PDF to my computer and then tried to reopen that same PDF to edit. This is where the problem occurs. I am only able to add text in some jibberish language and not the Arial font already set on the PDF. What is the fix to this as it's very frustrating??

Another issue is after making substantial edits to the doc, the system then crashes and the file has to be closed and reopened in like a save mode.
