Product count incorrect

Hi guys,

Can anyone help me figure out why the number of products is incorrect with respect to its category?

I have 3 products but the category is showing a total of 6 products?

as shown on here under the 'Bullguard' category:

Are you using any category mods?
try deleting the system/cache data and see if that fixes it
