Pro Gallery - only 9 of 12 images loading in a container with scroll

Question:
I seem to be having an issue with a pro gallery, it is in a container with overflow content set to scroll with scroll bar set to not visible, the gallery will only load 9 images. How do i fix this?

Editor X - Pro Gallery

I want to be able to scroll the gallery within the container

I have tried everything adjusting all the setting with regard to the container and the gallery - in preview it works but on the live site it’s not visible.

I am having the same issue right now.
Were you able to solve it ?

Thanks
