Project submits successfully, but curriculum does not advance

I’m working on the Request Header Parser project. All tests pass, and I can submit the project fine. However, when I view my progress in the curriculum, the project is still unchecked.

have you pressed the “Submit” button that appears in the modal? you need to use that to submit your projects

Yes, the project submits. The problem is that it’s still not checked off in the curriculum section, as if I never did it. I’m now having the same problem with the File Metadata project.
