Queries about ADV3227

Hi, there

I'm using ADV3227 in our products now and meeting a strange problem.

ADV3227 works well when it switches 10 channels. But all outputs are signals which is employed to Input 15 when it switches 11 channels.

I used AD8115 in previous deisgn and AD8115 worked very well.

I am not sure whether ADV3227 has this problem while AD8115 doesn't. Could you please help guide on this?
