Layering issue with classes

Hey everyone I am currently coding a drag and drop style game where you drag a seed to a target and it plays an animation within the seed movieclip. I am using classes to import instances of the see onto the stage and the problem I am having is that the animation plays on top of everything on the stage in my .fla file. Is there a way to have the animation play under a layer on my main timeline? I’ve tried to find an answer to this problem but to no avail. I have attached my files and would appreciate any help!

thanks a bunch!!
