SharePoint 2010, Tags and Notes: Count of notes does not match the number of notes displayed

We have a SharePoint 2010 installation, our users are actively using the Tags and Notes features with content on the site.

However, we've seen one page instance where the count of notes (both in the UI and what's returned by the SocialDataService.asmx) does not match the count of notes that are displayed on the page.

Specifically we're seeing that the UI and CountCommentsOnUrl Web method return a count of 3 notes. However, only one note is displayed in the UI. Additionally, the GetCommentsOnURL Web method returns only 1 note, and the Manage Tags and Notes interface in Central admin also returns only 1 note for the URL in question.

Any ideas what could be happening here?

Thanks in advance!
