BitBucket "Overview" tab is missing some Git commits...

I pushed 2 Git commits to BitBucket an hour ago, and one more
commit a couple minutes ago. The commit of the 2nd push shows
in the "Commits" tab at BitBucket, and in the "Overview" tab.

However, the 2 commits of the first push show only in the Commits
tab. They are missing from the Overview tab.

See https://bitbucket.org/fredstluka/hhl

The missing commits are:

• https://bitbucket.org/fredstluka/hhl/commits/783c4ac5ce431ef7afd430ec0381961282855943
• https://bitbucket.org/fredstluka/hhl/commits/d674f06638841ff4e76894cfc64e64c0df5d4270

Seems like an odd bug. Don't they both pull from the
same Git log?
