Collection list - items not showing

Hi all, not sure where to post this as not entirely sure the basis for the issue… I’ve created a collection list on the homepage of the site, to showcase a selection of products from the shop.

I am using Clarkson which had this module pre set. Unfortunately the help team told me the element was corrupt and to delete it. When I try and create a new collection list, the following is happening:

All i see is dotted purple lines and ALL the products appearing (but not imagery)

  1. I’m trying to work out why products are not showing in these purple boxes (I can confirm all products are published)

  2. Trying to work out how I just show a few products, not all. I really just want to show 4-6

Many thanks in advance.
