I'm sure this is some obvious setting that I cannot find, but I've had no luck after consulting the documentation and settings so here goes.
In the Control Panel for Expresso Store 2.0.6, I do not have any options available to edit the products in 'bulk' via the Inventory tab. Several hundred products are listed and paged correctly, but the table doesn't look like this screenshot from the documentation - it's missing the 'plus', sale price and sale price enabled columns, and my price column is a fixed value not a form field.
Any ideas why this might be occurring? I'm using Store 2.0.6 as upgraded from 1.X.
