k70 rgb rapidfire Holding 2 keys don't work?

Hello, I've been having a problem with my K70 RGB Rapidfire keyboard and I thought I'd post for some help/support. :)

At first I thought it was a anti-ghosting issue or something but basically here is the problem.

With my old cheap membrane keyboard if I held down 2 keys at once. For example 1 and 2, it would do this "12121212121212121212121212121212"

Now with the keyboard I am current using (K70 RGB Rapidfire) if I try to attempt to do the same thing it will do this "122222222222222222222222"

I was told it was not a anti-ghosting problem and to check for oddball settings in CUE, but I checked CUE and everything looks good. I don't know what to do and it is making gaming very hard for me :(
