after 2.3.1: Category product count not right

-- url of the page with the problem -- : directduchinois.ca/
-- HikaShop version -- : 2.3.1
-- Joomla version -- : 3.3.0
-- PHP version -- :5.3.28
-- Browser(s) name and version -- : all
-- Error-message(debug-mod must be tuned on) -- : Error_message

I am having a weird problem. The count of products per category is wrong on the first level.
Once I click on the first level category, then the sub-category count of product are right.

EX: furniture (10)
If I click on furniture, then I have
Sofas sectionnels pour la région de Montréal (22)
Ensemble sofa,causeuse et canapé pour la région de Montréal (5)

So the total should be 27 and not 10.
As well, on the right module, the same category is showing twice.
Ensemble sofa,causeuse et canapé pour la région de Montréal (5)
Ensemble sofa,causeuse et canapé pour la région de Montréal (5)

I have restore to the old version and everything looks ok.
Is it possible there is a corruption in the DB of products and association to category.
Thank you

A1. worked great! Thanks once again!
