Links also showing on Category page

This is a really useful plug in and has given me pretty much what I needed.

I have one problem:

I have been experimenting with the Related Links plug in with the Fanwood theme. The links are appearing as expected on the post, but strangely the same list of related links also appear in the Category page in which the post was listed first.

It only happens with the first post (and any additions to the related links in that post also appear on the Category page). Any new posts in the same category do not show the same problem (i.e. the related links are only on the post page and not on the Category page).

Any ideas if/how this can be fixed?

Thanks
