Why is it that direct messages are showing up in search results?

[PumpinIron]

I'm trying to figure out why it is if I click on a member's profile, go to the "postings" tab, and then scroll through all their posts, it also shows results for things they've said in direct messages (conversations):



I don't think it's add-on related as I don't have any add-ons that affect conversations to my knowledge. The only search plugin I'm running is XenForo Enhanced Search.

Thoughts?
