one column page option displayed wrong

I don’t know why if I choose the one column page option the content is aligned in the center instead of the left https://conadeip.org.mx/?page_id=85

I’ve already done the same thing in other blog and it works perfect!

Can any one tell me what’s wrong with my code?

Thanks!
