Modals open sometimes, sometimes not?

I have a site with custom modals opening with interactions. I am having strange intermittent behavior. They open sometimes and sometimes not.

Any help would be greatly appreciated.

Did you build the interactions yourself or are you using a template?

I pulled them in from here.

I have checked, and the naming conventions all seem to be ok for the interactions on the modal and the close. I noticed that the lightbox on the rental bike cards are not launching either.

I am about to delete all of the modals and try re-adding them and dumping the content back in once I have them all working for each card.
