Pro Tools cannot recognize 7.1.4 multi-channel aax plugins made by JUCE

I made an aax plugin with JUCE, supporting 7.1.4 at most(using create7point1point4), but Pro Tools recognizes my plugin as multi-mono plugin, not multi-channel plugin…Is there a way my plugin can be recognized as multi-channel plugin?

Are you using the SDK version 2.5 and a recent version of Pro Tools? If not, make sure everything is up-to-date.

I was using AAX SDK 2.3.2…I just updated it to 2.5.1 and solved the problem. Thanks~
