Ah, I'm not sure I was clear on that. You need to set the tasks for the project to repeat. The overall project will repeat, but it does not automatically make the tasks under the project repeat. As it doesn't know when you want them to repeat. For example, you may want some of the tasks to repeat at a different interval than the main project.
So 1) Create the project 2) Create the tasks you want to repeat under the project. 3) Set the repeat for each individual task. 4) no need to set the repeat on the project itself.
Let me know if that makes sense. Thanks!
