you should rectify the 1 error in i see on the picture as that could be the cause, secondly the mouse look could also have an effect, what object are you rotating with it?, thirdly the prefab itself could have an awkward rotation so you might have to set the rotation in the "create object" action, fourthly in reference to his second solution, theres an action called "next frame event " which is used to avoid events overlapping or overlooping in a single frame and so it causes the event to take place in the next frame
