Effects not showing up in editor

I’m using a water fountain in my level and there’s a water effect that makes it look like water is coming out of the top (from the Infinity Blade Grass Lands content in the marketplace). It shows that the effect is there(1st image) but i cannot actually see the effect until i build the level and play it (second image). It happens to textures as well. There is a texture for moving water (from the Water Planes content in the marketplace) and when I’m editing the level it does not move but when i build the level, the water moves. This was not happening a few days ago. Is there a way to make it so i can see the moving parts when i am creating the level?
