Remove "View e-mail in browser" or style it

I have made my own template and when i do a Preview it looks ok. When I send it to the test group i got a very ugly "View e-mail in browser" intop and before the content. How can i remove/move it or style it...

See image...

Another question is; Why don't the auto-preview work with my template? Do I need the tag data-builder="bg" in all tables (even nested?)

All the best
