Word 2007 numbered bullet points - spacing

[otuatail]

I am writing a comedy scene outline using bullet points. The problem is that when I get to bullet point 10 I get the text moving inwards like it has been tabbed. If I remove a bullet point sow that point 10 becomes point 9 then the extra spacing is removed as it is now bullet point 9

I have had it create extra spacing between each line. Microsoft's apparent default.
