Updates overwrite this page. Some may already be fixed since the last update: check RecentChangesLinked.
When incremental dumps and the bot work as planned, items fixed before 07:00 UTC disappear in the next update. The report is not updated if only the item count changes.
The report can include false positives. No need to "fix" them.
