Thanks for the feedback!
Note that there is also a macro (created by Doug Robbins) which will reset the character formatting for all lists in a document:
Code:
Sub Fixit()
'Macro created by MVP Doug Robbins
Dim templ As ListTemplate
Dim lev As ListLevel
For Each templ In ActiveDocument.ListTemplates
For Each lev In templ.ListLevels
lev.Font.Reset
Next lev
Next templ
End Sub
