Extra Fields for WooCommerce Data Fields

being DBA I like to keep my data in WordPress/WooCommerces tables. please don’t tell me this has its own set of Additional fields? I liked to know if I stop using any plugin my data is in the normal tables. not to mention I like to keep my tales clean and optimized.
SO, love the Feed plugin so far. But,
> I turned on that Add GTIN, MPN, UPC, EAN, Product condition, Optimised title, switch,
> I added the Extra fields Brand, MPN, UPC and some others.
> I looked in PRODUCTS|Atrributes and NONE of the fields are there just 2 I created.
> I need these extra fields in Attributes because I import from another system to Product Data linked by SKU to update Brand, UPC, MPN etc…
Also in the Feed plugin I thought I would redo the settings, uncheck ‘Add GTIN, MPN, UPC, EAN, Product condition, Optimised title, Installment, Unit measure and Brand attributes to your store:’ and all the extra fields, but ‘Add GTIN, MPN, UPC, EAN, Product condition, Optimised title, Installment, Unit measure and Brand attributes to your store:’ was back on when I can back in after exiting the plugin.
> then I created a NEW PRODUCT I don’t see my attributes in the GENERAL TAB only the drop down under Attributes.
> Love your product it really y help with Google A+++ guys. So what is wrong here, am I assuming something wrong with attributes, is WordPressed Jacked up not showing the fields like it should. I really need there extra fields to show for importing and to used with your product Feed plugin. Any help ould be great. Tinaswarehouse.com HELP!
