Hi Tyler,
Thanks for your help! It was indeed a VC problem.
The cause was a row that was only visible on mobile devices (in lieu of the slider) that seemed to be showing through. We have recently updated our VC so maybe it was something to do with that which caused the error.
I have deleted but will need to set this row up again at some point. Hopefully it will work correctly in the future.
Thanks!
Ieuan
