modules are offset

so there are a few things wrong and im not sure what i did.

1st. on the main page of my website www.projectlevel.org the "Content" module isn't lining up like on the demo

2nd. the right module is underneath my "content" module how did that happen?

3rd. why is there so much space at the bottom of my site?

possibly i did 1 thing to offset all three things, please help...

It looks to me that you are not using Front page Blog Layout/ front page menu item type for home page menu item , can you first check that.

All I did was copy the demo data I didnt do anything different from the kesha articles other than unpublished it

You perhaps did an inappropriate copy-paste in articles Marketing, Visual, and Music. Please delete everything from those 3 articles and put text again inside. Make text plain by copying to the Notepad first (or TextEdit on Mac) and then from there copy to Joomla.
