Button from Base Layer SHowing up On Other Layers EVen though Hidden?

Most definitely! Love that you embrace "Each One, Teach One"! 

I do have another issue that I'm struggling with, so apparently I'm still missing something with triggers and conditions. Hoping you might offer a quick explanation of what I'm doing wrong here. (I've uploaded my slides of a Drag & Drop Knowledge Check and a Multiple Choice Knowledge Check with a couple of placeholder "A" , "B" and "C" slides in between so you can see/test the Next and Prev buttons).

Again, restricted menu and resticted navigation required. Must get the Knowledge Check correct before moving forward and should not have to answer the question again upon revisit. (A results slide is not needed). I have set the slides to Resume Saved State upon revisit.

Issues:

1.  If  the learner submits the incorrect answer, clicks the Retry Button, they return to the question on the base layer. Nut...if they choose to hit the Prev Button to go back to look at earlier content before they give it a "ReTry", they the Next Button opens up and they are able to advance without answering the question/drag&drop correctly. 

2.  I've also noticed that at times, if you do nothing for a minute, the buttons will fire automatically, so somewhere I feel like I have something tied to the timeline erroneously too.

If you could point me in the right direction, I would be ever so grateful!

Thanks!
