Design content not fitting properly from template

Hello

Straight out of your design templates this > Dashboard - Brand

Is not fitting content properly as you can see the main page is not fitting on left side properly , same with responsive

Any ideas why this is please

You have added fixed-top class to your nav, take this out and you should be ok

Ah I know why now. (Yea I figured after some test) Thanks
1, If I select Nav bar to be fixed at top, it throughs the content off.

I need a side column to be fixed, or a way that links in the nav bar remain on screen.

Why cant I have a nav bar on side like this that doesnt break content?
