Contribution showing on my graph but no commit details are showing

My commits are, showing the in profile graph as below

But when I try to see the commit details, nothing found as below

New commits are showing as usual but I can’t see commits before a specific date. Also, I check the email address and username. Also I have gone through the article Why are my contributions not showing up on my profile? and all my settings were as it should have been.

Can anybody help me with how to get previous commit details and what am I missing?

When I look at your contribution graph, I can see contributions back to early January 2019 (I didn’t check before that). Some of them are shown as contributions in private repositories, but that’s not the result you’re describing.

Are things working properly for you now?
