Marketpress Add New Product Addition Options not needed (color, related products, cross-selling)

Marketpress > Multisite > Fullwidth Theme

New Product for shop owner section

I am using Plugin > UB;
which is wonderful for a fast css edit of the back end.

I'm trying to get rid of: Related Products, Custom Colors, Cross-selling.

I've been looking at the source code to try and figure it out.....but....no luck....

THESE CODES are NOT working:
.relatad_products_id_metabox {display:none;}
.mp_product_link_div { display: none; }
.mp_product_variations_table { display: none; }

Any ideas? How can I fix this? Thanks.
