Hiding Layers when Returning to Base Layers

I am using the Drag and Drop Video Loader Template.  I am having layer/base layer problems.  I have seen this tutorial about hiding base layer objects.  However, my problem is that everything looks good on the base layer, initially, then when I open another layer and return to the base layer, the images and text are now overlapping on the base layer.  I have hidden all that I should hide in the base layer and these other layers still appear.  One one layer, they disappear after about two seconds after I return to the base layer.

Is there something I am missing?
