As shown in the images, I am Diamond 1 (and have been as of 2 weeks ago.) My profiles home page, however, displays Platinum 3. This is only a minor inconvenience, I just want to help :)

I think you just didn't refresh your profile. It shows the right rank for me on your profile. It currently doesn't auto update it on the profile, but I'll make sure that will be added soon! Good find, thank you!
