I moved to MT from HI last July, my employer based in HI withhold only HI Income Tax, my W2 only shows HI. How do I file?

I filed the Partial Year / Non-Residency form in Hawaii, and corresponding forms in Montana.  MT accepted my return, Hawaii rejected it and stated my employer must update my W2 or I owe all liability to Hawaii.  Other employees at my company are in the same situation but are not having their returns rejected.  I fear if I merely accept the loss of my return and pay the newly appointed tax liability Hawaii has told me I owe that next year I will be in the same situation that I am not a resident but paying as if I am a resident basically in two states.
