CMS changes affects all pages

I’ve been designing a portfolio website using one of the provided templates in Wix studio. I want to make different pages to display different kinds of projects. but when I try to change content on one of the pages, the changes reflect on all the pages connected to the CMS. And when I unlink the page, it makes the webpage static. How do I create unique pages using the CMS?

What have you already tried:
I’ve tried unlinking the webpage from the CMS collection but it makes the webpage static.

Create a few more dynamic pages (depending on the type and amount of content that you plan to display on them), customize their layout as your project requires, and connect each page to the database in which your work is stored, set a filter on those pages where you plan to display a certain type of content (tag, keyword, category) so that on a specific page (let’s call it a template) a certain type of content from your database is displayed.
