Add Mapping Context and wait input press conficting?

I want to design a gameplay ability: when I activate it, a new mapping context will be added to the palyer and removed until I end the ability.
BUT If i put Add mapping context in front of wait input press, Wait Input Press would automatically trigger OnPress delegate.

Hi, I don’t know if you figured this out yet, but my solution was to drag out of the “Options” pin on the Add Mapping Context node, “Make ModifyContextOptions”, and ensure that “Ignore All Pressed Keys Until Release” was checked. That should solve your issue hopefully.
