Matt is spot on with the desktop issue!
For some further context, layout 351 only needs two different animations to function.
In your Timed Animations they will likely come from Relume titled as:
Layout 351 accordion [Open] [Desktop]
Layout 351 accordion [Open] [Tablet]
Also make sure the div/element triggers have the correct animations:
layout351_accordion div:
Layout 351 accordion [Open] [Desktop]
layout351_column:
Layout 351 accordion [Open] [Tablet]
The Tablet animation with that title in your interactions panel looks like it might have accidentally had a couple of steps erased, as the Tablet animation should have 4 steps instead of two. (It looks like a copy in your animations, Layout 351 accordion [Open] [Tablet] 2, is the correct animation.)
This should fix the tablet and mobile versions too!
