Restricted navigation within layers and alignment with base layer

In addition to Normal, the Chevrons have these states: 

• Hover: This automatically shows when the user mouses over the object.
• Selected: Typically, this automatically shows when the user clicks the object. Because the Chevrons are in a button set, only one can be in the Selected state at a time. However, there are triggers that change a Chevron to the custom Done state, which prevents the Selected state from showing in some cases.
• Done: This is a custom state used to indicate that the Section is completed. 

There are T/F variables (Section1, Section2, etc.) that also track whether a section has been completed. These are used in trigger conditions.

Personally, I think having the extra layers for some sections make it a confusingly complicated slide. I suggest re-doing the entire scene. Have a Sections menu slide that links to separate slides for each section. Use layers on section slides as needed. 

Here are some posts that might help:

Would like to add that I do not understand certain Chevron states and their purpose, as I took this e-learning from my predessor and have no contact with them now. May be the states were created to facilitate what I am trying to do.
