Help with CMS collection template

Hi,

I have purchased a template with CMS from Webflow and am trying to make some changes to the work template. However, when I completed my KOL Lab case study and moved on to the Porsche one, everything I changed in the Porsche case study also altered in the KOL Lab one. I also tried to add classes and IDs, but those classes and IDs also changed in the previous case study. Is there any way to solve this?

I tried to put my case studies on static pages, but I can’t link them thru the work page. So they all end up linking to the same case study.

Thanks in advance.
