This question already has an answer here:
When I click the Github button under Open Source Contributions, I only see my own repos and a couple of the repos that I have made contributions to; there are about 5+ other repos that I have made contributions to which are not showing up at all, and I can't add them manually using "other". Furthermore, there is no difference in the couple of non-owned repos I have contributed to that DO show up, and the others that DON'T show up; I made just as many, if not more, contributions to the ones that are missing.
How can I fix this? Is there no other way to manually add Github open source contributions?
