Help - Blueprint interfering?

Hello, I have a problem, next: I created two interactions for my scenario, the first is to open and close the door (Left click Mouse) and the second is on and off the lamp (Left click Mouse also), when I click to turn on the light, the door does not work anymore, but, when I click on the door the light comes on. Would be the blueprint interfering? (Sorry for the English, I’m Brazilian.)
