Enabling the ADV7802 Anti-Aliasing filter drives DP out of spec

When I enable the ADV7802 Anti-Aliasing filter (13MHz or 21MHz) the Differential Phase goes out of spec (1 to 1.2%).

 

The filter bandwidth don't agree between the SW and HW manuals - SW manual lists 10,13,16 and 21MHz, but the HW manual lists 6.9,10.5,13.4 and 21MHz.

 

How do I use these and keep the DP in spec? What are the correct BW's?

 

If I cool the ADV7802 with quick freeze it DP comes into spec nicely!
