Thumbnail Grid : How do I put classify my projects in different categories ?

[Mariannep]

Hi everyone,
I feel like I'm missing a piece of information and I don't know how to google it to find the answer I'm looking for !
I watched the tutorial to create a thumbnail grid and it's perfect, it's exactly what I need.
However, I need to create three pages for threee types of projects ("PRESSE", "PROJETS", "MOBILIER").

My projects are already dispatched in folders with those names in the project area on wordpress.
My issue is when I select "Show projects of category", it seems like all my projects are in the same category ("PROJETS"). All the other categories appear as empty, and the "PROJETS" adds all the thumbnails mixed together.
I'm at a loss ... Where should I specify which project belongs to which category?
I tried adding etiquettes but it doesnt seem to be working.
Thanks !

Hello Armin,
YES!! I cant believe I missed it, it was right under my eyes.
Thank you so much for your quick reply.
I designed the website in 2020 and I forgot what was part of the original wordpress and what was a plugin. That plugin definitely got me confused.
Have a nice day!
