Show Layer Triggers Not Working

Hi!

I'm working on a page where I've created six hotspots for learners to click on. Each hotspot should show a different layer when it is clicked. This works fine when I preview the slide, but when I upload the course into my LMS, this slide doesn't work. 

This is odd, because I use the same functionality on other slides and it works there. In the LMS, my arrow curser doesn't change into a hand to signal that there is interactivity where my hotspots are. This does happen in preview. 

I thought maybe there was some trigger order or object order that could be causing trouble, but I wasn't able to find anything that might be the cause on my own. 

Any ideas about what might be causing the problem?

Thanks!
