Johanna:
Richard is 100% correct and has given you a solution that will work.
However, to clarify further (for you and anyone lurking)-- the value for "ending punctuation" in a paragraph style refers to punctuation that will be inserted (if there is no other punctuation written by you) at the end of THAT paragraph, not punctuation that would be inserted for a previous paragraph. For example, in your Question Paragraph Style, you have ? as the ending punctuation. That means whenever you insert a new paragraph AFTER a Question Paragraph, a ? will be inserted if you have not written any other punctuation at the end of that paragraph.
Therefore, when you press F4-L to insert a New Line Paragraph, you are ending the the previous paragraph and that paragraph style's ending punctuation value is inserted.
As Richard stated, if you do not use another paragraph style, but instead insert the <New Line> format symbol, you are directing CATalyst to insert a new line within the existing paragraph style, and therefore no ending punctuation would be inserted, as the paragraph has not ended.
