Your first widget is using an H3 title heading within the content itself within an advanced text widget, while the others are using a text widget and the headings you see there are the actual Widget titles of the widget. Try changing the first one to a text widget and use the title field for the title.

There’s a lot of tags that are causing some issues from what I can see, so you may want to go in there and change all that. The complete bottom2 container is wrapped in a font size of 4; not sure how that is showing there because that means it’s being put in there by a plugin or it was modified in the theme files. Might want to start fresh without those and then if you need your fonts resized, use css to do that.
