Some Conference calls recording to different directory

Using FreePBX Distro, I am at 10.2.0.8. All of my calls and some of my conferences recordings are in var\spool\asterisk\monitor (expected)
but most of my conference calls are recording in var\lib\asterisk\sounds (not expected!)
Can someone explain or tell me how to fix? I have high call volume and it had filled up 80G of my hard drive before I spent an hour finding the culprit.
I am also wondering how other users handle large volumes of recordings that can fill up the disks, I currently just use a samba share and pull the recordings off to a larger storage area.
