Large gaps at bottom of pages in Fixer theme, help!

Hi Support

I have tried to manually fix this but I'm unsure what I'm doing wrong. I am trying to remove the excess space at the bottom of three pages, here are the pages that have extra space.

I'll post a couple screenshots so you can see what i'm seeing.

Thanks,
Martiel
