ES 2.3 Similar Threads and Resource Manager Threads

[mjda]

I just recently started using the resource manager on one of my sites. Today I noticed that none of the threads that have been created by the resource manager have a similar threads widget. Every other thread on my site has a similar threads widget. Also, none of those threads are showing up in other threads' similar threads widget. Is there a setting that's off, or something I can check, for this? I have 3 different threads that, to me, should probably all show up on each other's similar threads widget. In fact, if I use the search bar to search for a specific thread title, the other threads will show up too, so I'm not sure why they wouldn't be considered similar.

Anyways, it could just be that they don't match closely enough. I just wanted to ask to make sure I wasn't possibly missing something.

I did verify that "All forums" is selected in the widget itself.
