avatar not showing in "user list" of BP group chat

hi,
1 - i am trying everything under the sun but cannot get avatar to show in user list of BP group chat.

i tried changing avatar from Gravatar to png upload because i read that someone had issues with jpg.
i tried changing "Show Users List Position" for "settings page" and "settings site"
then i set them all back to default.

2 - besides the "BuddyPress" tab under "settings common", do the other "settings page" or "settings site" change the default style/functions of BP group chats ?

details:
WP multisite-BP-chat activated on main site(not network activated)-i am superadmin-access granted

any kind assistance would be greatly appreciated.

kind regards,
RC.
