Can't design cart page and login page

I am having a few problems with this plug in so far. 

 

1. I am deisigning the cart page but the live version does not look like the version when using the backend version. I also get issues with the coupon code button and the update cart button. When I design it from the backend it looks good but when I use the newly designed cart page the 2 buttons get really scewed. Take a look at the two pictures. 
2. When I design the login page I can not design the very ugly looking “register or login” header. The rest can be designed but that already looks OK. What that can be deigned already looks good but the header that does not look good can not be designed. Really fustrating! See the login page here: https://pianorgel.se/mitt-konto/
