Hidden state change occurs on wrong layer

What I would like:

I have a slide with five layers, the base layer and four additional layers. I would like the "next" button (which is hidden) to only be visible on the base layer AFTER all of the four superior layers have been explored.  

My Problem:

Using True/False variables, I have set the "next" button to appear only once all the variables have their values changed (with the trigger being a variable change of any of the four variables).  However what happens the next button gains visibility only on the layer in which it was triggered, and going back to the base layer hides it again. 

I tried setting the event to trigger upon clicking of any of the layer links, and the result makes the the next button visible on all the layers EXCEPT the base layer. Which is especially strange considering the "hide options on base layer" is on in all of the slides anyways.

I have also played with the settings for resetting/resuming initial state upon revisit and that did not affect anything.

Any ideas on what the problem is?  I have explored the thought of making them separate slides, but my project is complicated and I like the simplicity of it all on one slide if that is possible in this situation.
