Reply to x1 with defect??

I already posted it on NI community have 50+ views and no replies, so I'm posting here may be somebody help me

Today arrived my X1 mk2 and F1.
Well, I've been testing them today and x1 mk2 touch strip is not working properly, when I move my finger sometimes it works sometimes not.
If I put my finger in the center and make the move to the right or left for her to stay only one deck, nothing happens.
Has anyone had a problem like this?

Tested in traktor 2.6.3 and 2.6.4
I use Mac OSX Mavericks DP8 <- may be this is causing this problem?

Later not work with this, I format my mac, and fresh clean install mountain lion, install the updates of osx and later traktor 2.6.3 and the error persists, updated to 2.6.4 and same thing.


Here a small video with this problem
