Help with second master page

I am not really sure if the forum is used for support or email or what so I am posting here as well as sending support email. When I add a second master page, https://www.screencast.com/t/3ZmUrC564 the styling for the header gets messed up, not only for the new page, but also the previous header on the original master page.

Before Header - https://www.screencast.com/t/zKLUCYfO

After new master page has been applied - https://www.screencast.com/t/zKLUCYfO, this is the same page as above

New page page header - https://www.screencast.com/t/y0fBJ5iHJ, same spacing issue and but also the home menu is messed up.
