My guess is that Reigns not Khan is to blame.
IE Roman's pretty much refusing to show up again until Royal Rumble on PPV, due to his egomania and Bret Hart level refusal to lose.
Wonder if the rumor is true: that Hunter called his bluff towards Roman refusing to put over ANYONE or drop a belt clean. And that the War Games match will be Bloodline minus Roman versus people Roman's buried (Kevin Owens, AJ Styles, Matt Riddle, etc) over the last couple of years, with the stip that Roman loses one or both titles if his henchmen loses. And Hunter dead set on Bloodline losing, to get the belts off Roman once and for all since Roman won't do the right thing and put someone over/make a new star.
