TOPIC: avatar dont show up on attendees list

when you click on ATTENDEES to see a list of who is going, the list loads then the avatars populate and expand the list. most times there are 5 to 10% of avatars that dont show up on the list???? page refresh proves an additional missing bunch of avatars and some often are missed????? from time to time all avas show up???? Is this common occurrence or something wrong with the way my site runs. The attendee list is where most members peek just prior to signing up for events. I was going to just wait for the new release but thought I would check if there was a fix or issue with my methods. Jomsocial 1.8, dtreg 2.6.9b2

A curious note to all of the avatar loading issue is, when the list is summoned via the event registration page Attendee button the missing avatar shows up. but from the page with the missing avs' clicking on a profile sends you to jomsocial profile of that member then upon a firefox 'back to the previous page command' the page loads quick and all the avitars show up.
