No Multi Tasking windows on T-Mobile Note 2

[TmobileT889]

I have multi-window and it works just fine HOWEVER I am only able to get 15 apps selected by tmobile, unless your rooted I think thats all available. I am updated to 4.1.2 version T889UVBMBA. I have been rooted on a different note 2 and was able to get use all pre-installed & downloaded apps on the multi-window, with a few not working mainly because they view better on a full screen.
