We have a page which has a amp-list bound to JSON data to display the subcategories of a category. In one instance it displays all the sub categories, but in another the amp-list doesn't resize to display all the items (unless you click or interact with them in some way).
Working: https://www.caresuperstore.com/kitchen-and-dining/kitchen-aids-ampd (13 items)
Not working: https://www.caresuperstore.com/bathroom/bathing-aids-ampd (shows 6 but actually has 12)
This only seems to happen when viewing it on desktop.
