Cannot sort products by date updated or created

Description

I have just updated to most stable release of commerce 2 and I cannot use the above to sort products by those columns. I used to be able to but now it isn't possible.

Steps to reproduce

1. Go to hit the cog icon both of product types
2. Click checkboxes for Date update/date created
3. reload products index page
4. Hit the Date Updated row column header and it doesn't allow sort by asc or desc

Additional info

• Craft version: 3.3
• PHP version: 7.1
• Database driver & version: mysql 5+
• Plugins & versions: commerce 2.1.12.1

Heres what I mean in the screenshot
