SetCanAffectNavigationGeneration not accesible on blueprint?

Maybe i just dumb but i cannot find it in character or pawn blueprint, but it seem blueprintable according to this link

EDIT:
I check the pawn.h and i saw this
UFUNCTION(BlueprintCallable, Category=“Navigation”)
void SetCanAffectNavigationGeneration

As far as i undesrtood SetCanAffectNavigationGeneration is under Navigation, but in the header of the pawn class there is also this:
UCLASS(abstract, config=Game, BlueprintType, Blueprintable, hidecategories=(Navigation, “AI|Navigation”))

From what i can get here category navigation and ai/navigation are hidden… So i cannot access to SetCanAffectNavigationGeneration.
Is this right?

Found a workaround for the moment just using c++.

Thanks a lot for reporting it. I’ve made it right and cleaned the use of “navigation” category throughout AI code. It’s in CL#2354013

Cheers,
