Disabled Next Button will not change state to Normal when conditions met

Hi Heroes, I have an issue with the Next Button state not changing when conditions have been met. The Next Button is disabled upon timeline start. There are three paths which all return to the main slide once all slides in each path are visited. I have a Visited state on each clickable element with a variable change once all elements are visited. Once the conditions are met, the Next Button will not change to Normal. 

I did try this without the variable first, but came across this post (https://community.articulate.com/discussions/articulate-storyline/disabled-next-button-will-not-become-active-after-conditions-have-been-met?utm_campaign=elh_search&utm_medium=internal&utm_source=elh-referral). I'm still having the issue whether the trigger is the clickable element state change to Visited or the variable change.

I'm not able to share my content file, so I recreated it with some shapes and attached it for you to review. Can anyone help me find what I'm missing here?
