I have configured my product to be sorted and displayed by SKU on frontend.
I hvae products SKU like "G121" and "G1020"
everything is god expect that while logically "G121" that is smaller number should be on first page, the srting starts with "G1021".
You can see it here.
I want the products to start with smaller number and letter, like this:
G10
G20
G300
G1350
Thanks
