Hi Ashutosh,
Thank you for responding, I'm still trying to figure this out and having issues saving it. The changes have been lost which isn't such a big deal it's the saving part that I need to fix.
Version of OS is 10.13.6
Are you getting any error message while trying to save or export? No, Everything in the program is working normally except for when I try to save it nothing happens. If I use the command for save as it saves it to where I selected but it doesn't save the updated version I was working on.
Is it happening with this specific document you are talking about? Yes, I was working on two seperate documents and one of them did save because I just created it and started working on it yesterday. So I'm not sure if its the older document because it was made back in 2014-2015ish.
Is this document saved locally or on a network? I had this document on my mac for about 2 years now and used it as a template to create newer versions. I also have a backup on a network.
Update: The problem went away completely. Thank you for the help my friend!
