Layers not Hiding in Storyline 3 file when accessing course on LMS (Internet Explorer)

Hi, I've created a storyline 3 course and published it to our LMS.   I am seeing an issue with one particular slide where a layer is not hiding correctly when the trigger is selected.  This issue is only seen when accessing the course on our LMS using Internet Explorer.   The slide performs correctly Storyline 3 Preview and when accessing our LMS using Google Chrome.

I've also asked our LMS support team for advice but wondered if any Storyline experts experienced anything similar?  Many thanks in advance
