I have a 33-page doc that I created in ID. It has many links to URLs and email addresses throughout. I originally made this document last year and when it was exported to interactive PDF (for a11y remediation), all links were properly associated with the Link - OBJRs within the link tag associated with the link text.
I made edits to the document recently and now when I export to PDF, link text and link destinations are matches accurately, however, the Link - OBJRs are connected to links elsewhere in the document.
For example, I have a page of contacts with many email addresses. They all open to the email window ready to be sent to the proper email address, but if look at the Link - OBJRs they are associated with other links on the page or other pages altogether.
At the time that this first occurred, I was running my old machine and hadn't made any changes. I usually am running the latest versions of all the Adobe apps I use.
Side note: I am now on a brand new mac and the CC installation process was terrible. I downloaded CC and could only install a few apps. It wouldn't allow me to install ID, PS, and Illustrator. I had have Adobe support help me — they used terminal and did things I don't understand to get CC to install properly…an issue I wouldn't have expected to have with a brand new mac. It was quite frustrating and a big time-suck.
Anyway, I THINK I may have discovered the issue:
Last year when I made this document, I created the contacts page from scratch and added each person's emails one by one, auto-styling them via the hyperlink setup/character styles.
This year, I added some new contacts and used the eyedropper to pull visual styles for some of the links. I use the eyedropper a lot to apply paragraph and character styles in my documents. I think this created the Link - OBJR mess.
