Attributes not visilble on WC dashboard

I have a strange situation when compared to other issues I have read in the forum regarding attributes and bulk editing.

I have used the default bull edit option within woo commerce to add a new attribute to already existing products. After creating the attribute and the members I have successfully bulk added the attributes. I have also successfully added WC layered navigation widgets to my shop page which filters according to this attribute. But when I look at the backend, WC product details, attribute does not show up.

Has anyone encountered the same problem? I am using latest WordPress and woo commerce.

I will appreciate your help.
