Custom collection bug? Duplicating content

Hi Gliders,

I’m back and currently working on Glide Page, I noticed there is glitch or bug when Im using the custom collection. It shows or duplicate the collection (shown in attachment). Duplicated view appear on mobile, pc and tablet view.

thanks in advance.

Manage to find the issue, the main custom container and the collection list are using the same source thus resulting duplication of content.
I remove the source table (assigned other source table) on main Custom container.
