MySQL query not returning true value?

Hi folks, I am using the following MySQL query in my PHP script:

SELECT FROM_UNIXTIME(com_date, ‘Week %V; %M %X’) as week FROM comments GROUP BY week ORDER BY com_date DESC

The server is returning only 110 weeks, but in reality there are 129.

You can see it, here:
…you will notice it says only 110 weeks, but also page 7 of 6 (20 weeks per page).
