adding multiple motion effects on video

Hi there

I'm trying to add multiple motion effects to a single video clip. Essentially, I'm creating a drumming video and I want to zoom into certain parts of the drum set throughout the clip. I created the zoom using the motion effect, but when I add in more than one motion effect, they end up cancelling each other out, and there is no zoom (even though the "scale" shows up at over 100%). I seem to only be able to zoom in once. Any advice on how to add multiple zooms throughout the clip?

I posted an image below - as you can see, there are multiple "motion" effects, but none of them are applying to clip

Thanks
