Random missing letters appearing when editing and saving over a PDF
I cannot upload as the information is sensitive but there seems to be a programme glitch when you are editing and then saving over PDFs. I have just attached a screen shot instead. It happens maybe 8/10 times but when you are editing the text on PDFs random missing letters appear. It seems the only way to get around this is by copying and pasting the letters back in place and this doesn't even always work. The PDFs were originally designed in Indesign and saved out as PDFs as templates to be edited afterwards. I have called Adobe many times and the issue is still occurring months later. I have tried re-creating the indesign files, I have tried changing the font, I have tried un-installing and then reinstalling, I have tried many other computers and this issue is still happening. It is a terrible problem and is happening to all of my colleagues. This needs to be fixed immediately as I have spent so much time on this bug already. It is extremely frustrating.
