Control Center Blueprint Not Appearing


I have two blueprints in Control Center and when I go to create a project, neither appear as an option. I've tried creating a duplicate of an existing blueprint but still am not presented with any option to select a project when creating a new project from CC. I tried checking an existing blueprint settings and when I get to the step to Save I'm presented with this error. Can anyone please help? This is preventing us from setting up project management tools for active projects.
