Hi
You need to increase the Hanging Indent you have set for each style so that all paragraphs still line up following the paragraph numbers. You can NEVER have the same spacing on all paragraphs because the number of characters increase when you go over 9. Right click inside your paragraph and choose "Paragraph". Then under "Special:" make sure it is set to Hanging Indent and set enough space as you wish to make sure their is sufficient space between the paragraph number and the paragraph text.
Good luck.
