Cannot see myself in the list of project contributors

https://github.com/pgjdbc/pgjdbc/graphs/contributors lists persons who participated in the project. Earlier I was in the list, but now I cannot find myself.
Proof: https://github.com/pgjdbc/pgjdbc/commit/eb6ca5c698b6c549443ccc99ac22c5c271835a6d can be found in the log of latest master branch:

git log --pretty=format:"%h %s %ae" --no-merges HEAD | grep serega.morph
eb6ca5c6 connectTimeout property support serega.morph@gmail.com

Insights Contributors says: “Contributions to master, excluding merge commits”, so it’s expected to be here.

Also I can see myself on the fork of the repo:
