Yes I believe I know what you’re experiencing with the flight planning. It’s happened with the new glass panel updates on the other CowanSims Ships.
Seems the same problem exists on the R66. I just did a quick test inputing a direct-to in the GDU/G3X, as well as the GTN650 and the CRS arrow remains at 360°N. However when I bring up the panel with the GTN530 (click the bar above the anti torque pedals) that input corrects the CRS arrow when going back and selecting the glass panel again. I hope this helps you “work around” it until the glass panels get full flight plan functionality.
