Append at start of content

Hi all.

I have configured the plugin for this page:

https://marcomiserini.altervista.org/isotope-2/

But the “load more” (or scroll) do not append the new image but put under other images.

I use the follow parameter

Navigation Selector: div.wp-pagenavi
Next Selector: div.wp-pagenavi a.next
Item Selector: .grid-item
Content Selector: #ms-container

Can you help me?

Regards,
Marco
