Leftover posts in /review first answers not being reviewed

Question

There are five posts currently in the /review section under the first answers tab that refuse to acknowledge I looked at them.

For example reviewing Facebook like button without iframe will show as

But on refreshing the page. The link returns.

I have tried editing or even placing a flag. Editing does not remove it. But it seems a flag does. Though this flag does not show up in today's stats.

For science!, I tried again with Remove the Chat box from the left pane on Gmail

A flag does indeed remove it from the review but not an edit.

Though the stats do not reflect the proper numbers.

The Facebook like button question returned (most likely because I addressed the flag).

Answer 1

This happened cause my implementation was a bit naive.

When removing posts from the global list:

1. I removed all posts that were reviewed by 2 reviewers
2. I removed all posts you reviewed in the last 7 days.

I assumed that someone else will review all the posts you reviewed in that 7 day window.

Clearly I was wrong.
