Did those paragraphs get a style applied to them? I expect they became 'List" so you need to modify the style settings for that style to get autonumbering on it again. It is not ideal to apply an a,b,c list as Heading 3 because that removes your ability to apply a real third level heading with 1.3.1, 1.3.2 etc

The purpose of the macro is to get consistent styles applied across your selection and then, if required, it is easier for a second macro to reassign a style (like convert 'List' paragraphs to 'Heading 3')
