Collapse Elements odd behavior on Element 1

I am following the WIX example https://www.wix.com/corvid/example/collapse-elements

I created the all the container boxes and arrows with the exact same names and properties. I used the example code copy/paste, with the exception of figuring out “onClick” should be “click” for the Event.

Elements 2-4 work exactly as expected, they expand when clicked and close when another one is clicked/expands. Element 1 however will not stay expanded. Sometimes I can see it expand for a fraction of a second and then immediately collapse. It will collapse elements 2-4 as expected. I’m a noob at this so I might be missing something simple, appreciate any ideas/help. Code is below:

Not sure why/how, but I added a 5th fold above the 1st fold. The 1st fold (now second on screen) was still the only one not working. I just deleted it and renamed the 5th to 1st. I must have boogered something up with naming or something. I swear I checked naming 50 times, but whatever I think I’m good now.
