Headings in Contracts Clauses do not match the font size of the numbers

Headings in Contracts Clauses do not match the font size of the numbers

When I set a line in a Clause to be a heading, it bolds it and numbers it according to the heading level, but it does not change the font size to match the numbering font. For example, Heading 1 is a 14-point font, which I have to adjust manually every time.
