Weird symptom.

I created several links on a PDF "intro" page that point to various pages in a larger doent. If I change any one line on this intro page - or even create a new link - the majority (but not all) of the other links on that page change to the same action.

E.G., I have some links that are supposed to just open a file while others go to a specific page in a file - if I change any of the links, they all end up changing the action to "go to a specific page".
