When creating hyperlinks within a document, certain links, although functioning within the hyperlink panel, do not translate as links when published online or as an ePub. This is completely random, as other links set up in exactly the same way (often on the same page) work fine. Have tried everything I can think of to fix the issue myself but can't figure out why it is happening.

Steps to recreate the issue:
1. Set up document
2. Set up multiple hyperlinks (mine are objects rather than text)
3. Preview in interactivity panel and/or publish online

Expected Result: Links should be in the document. Links should appear as clickable when hovered over.

Actual Result: Some links do not appear (randomly). This happens no matter what you do to try and change it. Even if you try adding various other links to the selected object, or adding the same link that works in other objects...some objects refuse to translate as hyperlinks in the published version.

I'm pretty sure this is a new issue, although I have tried reinstalling old versions of the software and the problem reoccurs. So have updated to the newest version again. Please help! Thank you
