sidebar issues!!

Have designed my site around the 'Church theme' template and have come across this problem.

If I click on any 'topic' from either the Nav menu or the sub nav menu the post is displayed correctly with the sidebar categories where they should be (see 1st pic).

However, if I click on the sidebar 'recent posts' any topic, then the sidebars end up further down the page, immediately after where the 'post' on the left finishes (see 2nd pic) and the copyright footer bar comes out of the theme border too!!

This one is beyond me so here's hoping someone has the answer to this as I dont recall changing any code in the sidebars
