Display Avatar plugin not work fine with Atahualpa theme

Hello and sorry for my English..

I have instaled:
W.P. 3.1.2 Alpha in Multisite mode.
Add Local Avatars plugin (VPeter Sterling ) 10.0
Display Avatars plugin 0.1
Atahualpa 3.6.4

Display Avatars show the post author avatar at the right area of each post and work OK in Twenty Theme but in Atahualpa theme show 2 avatars and change the title style.

The problem is just in multipost page. In a simple post it work fine but in the home (Posts page) show 2 avatarrs and the title style go away.

In the other hand I tried to show the avatar in posts only with ATO and Add Local Avatars plugin but always show on left.

Anybody can help me!

Thank you!
