How to get rid of 'example project'

Hi, this is probably really easy but I cannot figure it out: how do I get rid of the ‘Example project’ showing up in my project list when I select ‘all’ projects? It is not in the project folder, so it is probably called on in another file? Many thanks!

We cannot know, what is the “Example project” that you are referring to, without seeing the source code of your project.
