buddypress New Blog Post activity stream avatar

alright. i pretty much have everything working great. latest bp. latest wp multisite. 1 thing i can’t figure out though. avatars show up correctly everywhere in my sites and sub blogs, and widgets EXCEPT for new blog posts activity stream posts. for some strange reason, buddypress default avatars show up. any ideas?

fyi, i DO NOT have the Avatars plugin installed due to the conflict message here https://premium.wpmudev.org/project/avatars

thanks!
