How to unlink the text?

For my projects tab in my website, I have text that describes each project under the photo. “Project Details”
If I change the text in one project it changes in all the other project details as the same text. How do I make the text unlinked so each project will have it’s own “project details” text.

Additionally. When you click on the project tabs “All, Warehouse, Industrial, Retail, Religious, Service”
The photo that go to each tab should match up, but it goes to random photos. How do I correct the tab to match the project photos?
