The numbered paragraphs probably have "Space Before" applied.
Thanks for your answer Peter,
How does one do that? is there a shortcut?
Thank you Peter!!
Very helpful, got it!!
It should be defined as part of the paragraph style, but since the designer didn't seem to know how to set a left indent on a paragraph and started things with tabs, it may not be. There's a section in the style definition dialog called Indents and Spacing where you would do it. It's also possible that instead of space before for the numbered paragraph, space AFTER was applied to the paragraphs with the arrow bullet. Fields for space before and after are accessible in both the Paragraph and Contol panels, so if you put the cursor in a paragaph you should be able to see what is applied (but not whether it is local formatting or part of the style). You'll need to do some looking.
I would also re-define the styles, myself, so there are proper left indents instead of leading tabs (and get rid of the leading tabs using find/change) and set a next style cycle for the three styles involved in that list, so that if you type in new entries they will automatically rotate through the three styles for each entry.
