Making a Spot Light properly projects video textures into walls

Hi everyone,
I’m new to unreal and I need some help! I’m trying to project a video from a moving spotlight. I made 3 spotlights for each RGB channel and it only shows the video properly only when the lights are stationary. But when they’re movable, you can see the spotlight colors projected as well.
Is there a way to make them movable and remove those spotlight colors? I need the source lights to move.
Thank you!
