I have an issue with linking to bookmarks (from footnotes) in my word document which has only just started happening in the past couple of days.

I want to link a footnote to a bookmarked section in my document, so, I highlight the text and click hyperlink. I then select bookmark and then the appropriate bookmark that I want it linked to. However, when testing the link it links to that named section in the table of contents at the beginning of the document.

If I view the link which goes to the incorrect section it reads as "#Appendix 2 Manufacturers Literature".

However, I do have a link that does work and goes to the same section in the document, and the link reads different:

"#_Appendix_2_ Manufacturers_Literature".

Edit: Well, the second link did work but now it simply takes me back to the first page in the document when clicked, so, neither of them work!

Is there any reason that may be causing this? I have hundreds of links in the body of the document that appear to be working ok.
