Community profile asking me to create a readme, when I have one

Following the link over at Community · GitHub in the Checklist, I have the " README" coloued orange; with a link navigating me to About READMEs - GitHub Docs — but I do believe I already have a readme here meros/ at cf7625d675e86cc200e274914ada1438d182f851 · maraisr/meros · GitHub

I think it has something to do with the casing of the filename?
