Why position number does not affect products order in one category?, but it is not happening - the products have their own place in the list - How can I manage this?
You could try going to:
administration - appearence - customer settings and change the option Product list default sorting to default.
I think when this is default then the products are ordered by their position, but you can also change this to sort the products by price and name as well.
Thank you, it works
