Hey Jacopo, thanks for pointing this out. Yes this is something I haven't thought of and I should improve it one day. At the moment the project thumbnails inside a carousel don't update automatically when you change a project's title or its thumbnail. :/
At the moment the workaround for this is to edit your carousel and remove the project thumbnails that are inside.
So for example when editing my carousel, here I would click on "x" for all of them to remove them:

Then you would need to click on "+Add Projects" in the "Edit Carousel" modal and re-add all the projects.
