The dot appearing before the paragraph in your screenshot indicates that the paragraph has a format such as 'keep lines together', 'keep with next', and/or 'page break before' applied. That could be done to any Style - though it's quite common with Heading Styles and its use with a Heading Style appears most likely to be the case here. Check whether removing the relevant attribute from the paragraph format affects the layout.
