Answers in top Network Posts showing incorrect score

Question

There is already a question Top Network Posts showing incorrect score which is posted around a month ago (which was fixed). My question reports a similar issue of showing inaccurate scores along with another bug.

A couple of answers in the Top Answers in my network profile are showing incorrect score.

As we can see they are showing a score of 10. But as of writing this question, the score of both the answers is 9. First answer about marriage and second answer about withdrawing weapon both have a score of 9 instead of 10.

Even though the current score is 9, both these answers reached a score of 10 a few months ago and I was awarded Nice Answer badge for both.

The vote was removed either when a user was removed or there was an unupvote. As far as I can tell, I don't remember an unupvote notification in the achievement box from these answers. My guess is the votes are removed when user accounts were deleted.

So, I suspect the score of answers in Top Network Posts is not updated either when there is an unupvote or a vote thrown away due to account deletion.

Is this the right reason why score is inaccurate? Can this be fixed?

Confirmation: I'm seeing multiple instances of the same off-by-one problem:

• User Nog Shine on meta.SE

  • 54 Was Mjolnir ever used for building something? (actually 53)

• User Lun on Ukrainian Language top network questions are:

  • 12 How to transliterate 中文 in Mandarin pronunciation to Latin? (actually 11)

  • 8 How to transliterate 中文 in Mandarin pronunciation to Russian? (actually 7)

• User Ébe Isaac on Puzzling

  • 51 What should I do after advisor got upset when I expressed "belief in evolution" and then said he couldn't add me to his research team? (actually 50)

• User M. A. Golding on SciFi

  • 25 Who was Richard of York at the Battle of Grunwald? (actually 24)

• User Patrick Hofman on meta.SE

  • 82 How to remove the last element added into the List? (actually 81)

It's sporadic: not all posts have these problems. It affects both questions and answers.
