First of all, hats off to a well constructed, clever plugin.
I seem to be having an issue with the relation names repeating on a post / page, which is making it hard to manage for my client. For example, in relating News I have:
News Item 1 (60)
News Item 2 (62)
(Where (60) and (62) are the post IDs.)
I have played with '_relation.tpl' and '_relation_multi.tpl' to attempt to tweak. But the same thing happens whether I use [+post_title+] or [+post_name+] - the ID stays unique and the relation link is correct on the front end, it's just the back end where the issue exists.
Any help or advice welcome.
