Flickering moveable lights delay when setting intensity

I have this flickering light BP that uses light intensity to flicker a moveable spotlight and point light. Here is the BP code below:

When I have one of these lights in the scene, there is no problems, see below:

However as soon as I add more to the scene, the set intensity function becomes delayed and makes for some unsynced behavior with the “Set Vector Parameter Value” function. See below:

I do not recall having this problem on older versions of Unreal from a few years ago. Much has changed with lighting since though. Any recommendations to help remedy this issue? Or is this just an engine limitation?
