Help ! different youtube video on different project

Hi everyone !
I hope that you all are ok.

I had a small problem to resolve.
I bought a theme for my website.
I have several project categories and I would like to insert different YouTube videos on each project.
Every time I try to change a video for a particular project, it changes the video on all the different projects I have.

Could anyone help me?

I’m new to webflow…I still have a lot to learn but this would help me enormously.
Thank you in advance for any help you can give me.

I attached 2 different project page and unfortunately the same vidéo…
