Contribution graph shows all commit/pr in deep green despite actual code quantity

Hi, everyone:

I’ve been frustrated by the abnormal display of contribution graph. I have some work-in-process branches, so don’t want to destroy the repository and re-fork.

My profile is at You can see every commit has the same deep green color which is totally wrong.

Is there anyone know how to solve this problem? Thanks!
