Ok thanks for letting me know. All the best! 
Hey
you must understand how Dolibarr manage stock quantities inside llx_product and llx_product_stock
with your import you added information in ll_product_stock table, with the first field associated with fk_product, the second field asociated with fk_entrepot (or warehouse), and the last field as quantity
can you check that in phpmyadmin, with then llx_product_stock table
What you need now is to update the stock value in the llx_product table
the field containing stock value is named “stock”…
I think you can do this with another import …
Good continuation
