Wildly different rejection counts for same user [duplicate]

When I look at old suggested edits, and click on the (more) link to view the accept- and reject-counts, I get wildly different rejection counts (on myself) for no apparent reason.

Examples:

• https://stackoverflow.com/review/suggested-edits/6246790: 3 rejected edits (bogus)
• https://stackoverflow.com/review/suggested-edits/6246656: 47 rejected edits (correct)

At the moment, I can't seem to find a single suggested-edit with 3 straight approvals or 3 straight rejections that have the correct count. It seems to be the ones with mixed votes, or other-than-3 votes that have the correct rejection counts.

Is this a bug or is something else going on?

Note:

There is a similar question from a month ago:

• Suggested edits showing the wrong stats

But that was posted at a time when there was another similar bug which, according to comments, is believed to be unrelated to my bug report:

• 'Reviewer stats' on suggested-edits shows an incorrect information
