Wordpress MU and Buddypress breaks up In Post Ads and Comments Plus

Hi,

After activating Buddypress again (was migrating into MU) the In Post Ads are not vissible anymore on the website.
When I deactivate Buddypress they show up again in the posts. I was using verison 1.3.3, but also tried the beta 1.3.4-BETA-1 to see if that helped.

I have the same with the Comments Plus plugin. (I know should be different topic)
When Buddypress is deactivated the comment form is vissible again in all it's glory, when Buddypress is activated only the tabs can be seen. Also see the above link.

Before I migrated to MU BUddypress and and these 2 plugins were working okay.

Gr,
