Nested Multireference field on Static page


I am trying to make a nested multireference field in a static page (see link below). \

What I have is:

  1. Main CMS collection: List of lectures

  2. nested within each lecture CMS item there is an accordion to open a list of references for the given lecture. This is pulled from a separate CMS collection via Multireference field.

It sort of works, but doesn’t pull more than 4 multiref items.

Multiref fields work fine if in CMS template pages ( I have a plan that allows for 10 multiref items).

Hope someone could advice or I will have to link each lecture to their respective template page, where the multiref works as expected.

Here is the link for my page:

Thank you for your thoughts.
