Update Number of Comments After Conversion From vB

[Chris027]

Hi Guys - Is there any way to update the number of comments displayed below an article? The only way I've discovered is to add an additional comment, then the number is updated from zero. See image below. The top two articles display the number of comments because I added a test comment below the existing comments. The bottom two article show zero comments, even though there are plenty of comments listed when I click on the comments.
