Sorting products in admin – new products appear last

Hello,
I hope someone can help me. I have been trying to solve this issue…
I have a shop with woocommerece, and all the new products I add goes to the last page (on the admin) and it is slowing my down (I have many products).
I tried couple of plugins, and some code, but none of those actually fix the admin sorting problem!
It seems that the sorting is according to date..or ID.
Please help me solve the issue…
Thanks
