So I just realize that on my site. If a user change his avatar, then all of his listing under listing type "JOB" have listing thumbnail change to that avatar. Including listing that has picture and no picture. Test on demo site same thing. Please see here:

You will see that listing with title QA does not have picture but thumbnail taken from listing owner avatar. If you login to this listing owner dealer, pass demo and try to change avatar picture. The listing thumbnail will change accordingly.

At first I thought it was a bug, but after viewing flynax demo, I think its a feature since all job listing has listing owner avatar.
How do I disable this feature? I think it related to listing type key to only apply to job listing type?
On my site, most jobs listing has picture. I don't want it to change to listing avatar picture.

Thank you
