BUG Mod_virtuemart_product customfielsCart randomly result

[Mathalis]

Hello,
I'm using mod_virtuemart_product and need to used customfieldsCart.
I customised this module for my needed.
I display 3 featured products.
I have only 3 featured product.
Customized data for these product are displayed for some and not for the other.
Sometimes i have 2 product ok and sometime only one which display his customized data.
To be more precise,  the 3 products are always (fortunately) good ones
When I check $product var, I noticed I have randomly all customfields (related Catégories, and all others)  and sometimes don't have.

I think it's a bug on product model

Does any help about ?

Best regard.

Hugues
