Alignment of a layer moves up and down
I am having an issue with layers on a particular slide not aligning with the base layer or first layer. I have buttons/boxes that you click on in the base layer that display the various layers and I have selected some of the base layer to be visible. Layer 1 works fine, all triggers etc. work fine, but what happens when you click on the button/box to trigger layer two (and the same for layer 3) is that the entire slide view of the layer and background move vertically up a few pixels! Then when you click on the button/box to see layer 1 again, everything moves back down where it should be. This is not visible when I am designing the slide, only in preview mode. I've attached this part of my project.
