Modals for CMS are slowing designer and live site

I built a site where users click a cms powered card to pop a modal for more information. It seems like a common problem I can’t seem to fix, but the site is popping all the modals at once.

This is slowing down the site and making the designer unusable when the popup is made visible.

Any tips in fixing this? My site read only is below.

Thanks!
