tags in my event text are not spacing correctly, and are making the layout look sloppy.

When I add <h> tags to my text, it is screwing up my layout. Please see my example of what happens to the text under the word "LOCATION". It moves up and to the right. I want it to stay underneath the title and to the left. I can fix it temporarily by adding "br/" tags after the h tags, but if I go back into my event to edit it some more than all of my br tags disappear and the layout is messed up again. Please help!
