Collections - scrolling on page not working

We had our website built with the WebFlow team quite a while ago and since had a complete shift of internal management of the website which meant some errors are only being identified now.

Issue we would like to help with is: collection based Team and Trustees pages don’t work / scroll - the arrows that are meant to scroll you through the collection are inactive.

We tried to look into this but had no luck so far - any help would be very very appreciated!

Looks like you’re using splidejs for the slider, and that it’s misconfigured or some elements have been deleted.
