Help please with spacing of Ad blocks on right

Hello,

I have installed a theme – ‘PassionDuo_Blue’ – and put a header image in (don’t know if I have done this correctly but it looks ok) which has a bigger height than the original header writing.

I need to know how to make the ad blocks on the left go a bit lower, because they are covering up the navbar. I have tried altering many things but can not get it to show correctly.

Can someone tell me how to do this please?

Thank you for your time
