Thanks James!
I realized that I wasn’t checking the value chosen in the select option at all. I only checked if the fields had content or not, thus when ACF saved both values it was also showing them and breaking the page. I made an assumption that the plugin takes care of that since I set up that conditional logic for the forms but there is no reason for it to do that.
Test and double test before going live, clients are really awful beta testers.
