G2/G3 K values alarm out Doosan VMC

I've been learning how to use my Doosan these past few weeks. One thing that I've noticed, but do not understand is the Haas post's inclusion of a K value with my G2/G3s. The Doosan post does not include this value and actually alarms when it's included. What's even more confusing is if I remove the K value from the Haas post, the program runs on a VF2 without a hiccup. Does anybody have any insight?

Perhaps Fanuc ( on the Doosan ) needs the G18 ( X/Z plane ) selection in it's own, separate block?
As far as why the Haas would run with or without the K0 is because it can be omitted if the value is 0.
 
In Fusion there is a checkbox in the Doosan 3/5-axis post properties preferences to "Force IJK." The post seems to work fine either way on my DEM 4000. Make sure your cutter radius (not diameter - DAMHIKT) is correct in the control if you are using comp in the control, else the control may detect a gouge situation and alarm out.

This is a block without the box checked: G17 G02 Y2.9942 J-0.2968
This is the same block with the box checked: G17 G02 Y2.9942 I0. J-0.2968

Both Mastercam and Fusion posts seem to run without an issue. I think it might be something with the modified Surfcam post we were testing.
