This happens when you insert the entire clause text into the row meant for clause headers/titles.
Please see the image below for more details.
Text in the 'Clause Header/Title' row will appear bold and underlined in the actual CP. Text placed in the 'Non-title text' row will remain 'plain'.
You may solve the problem by shifting the non-title text for each clause to the appropriate row.
You may also freely add new clauses, if required, by clicking 'Add New Clause'.
