CMS "current case" pulling from other "cases" on portfolio site

Hi all!

In the course of me trying to set custom “cover” settings for the images in each image block, naturally this kept applying itself to all the cases and their items. I then tried duplicating the classes and giving them a name related to the case study they’re representing.

Cut to know, in section 3 of my cms I am trying to separate editing the settings of the content but it keeps mimicking across all pages.

Any insight here would be deeply appreciated!
