Changing the state of the "next" button back to normal not working after icons are visited

Hi Pamela! It's hard to know without seeing your file what's going on, so if you'd like to share it here I'd be more than happy to take a look.

Just a hunch here that it's possibly happening because you're using icons to trigger the layers. Generally when you use an icon, it's a series of freeform shapes and it's those freeform items that have different states, not the entire icon. You can expand the icon on the timeline to see if it has multiple components like I've done in this screenshot. Try replacing your icons with buttons to see if that fixes it, or adjust your trigger on the next button to change to normal when the state of whatever freeform part of the icon has a visited state is visited! I know that is tricky so if you share your file, I can take a peek and test a few things!
