Some troubles with products, updating, importing

[MagicFire]

Hi,

 

I have very strange mistakes. These things happen with XML import. It creates products, but there is some error (in BO->Product->Edit products), because in DB it says there are 100 pieces of each product but system says there are 0 pieces(or it even doesn't allow me to these tabs).

All that helps is to save over each product, than this error dissappear and I can fully modified info.

Does anybody know where could be the problem? Should I do something like update or refresh?

 

Because there are about 1000 products and I can't do this with each single one of them.

 

I'm using PS 1.5.0.17

 

Thanks
