Thanks Pierre and Rafael for the help on cleaning the list styles
For the record, the small piece of code is
--------8<----------
Sub CleanListStyles
Dim sFamilies as Variant
sFamily = ThisComponent.StyleFamilies.getByName("ParagraphStyles")
Dim newStyle as Object
Set newStyle = ThisComponent.CreateInstance("com.sun.star.style.ParagraphStyle")'
newStyle.ParentStyle = "Standard"
sFamily.insertByName("olivier_dummy", newStyle)
CleanExtraBullet("List 1", "olivier_dummy")
CleanExtraBullet("List 2", "olivier_dummy")
CleanExtraBullet("Heading Caution", "olivier_dummy")
CleanExtraBullet("Heading Tip", "olivier_dummy")
CleanExtraBullet("Heading Note", "olivier_dummy")
sFamily.removeByName("olivier_dummy")
msgbox "Finished"
End sub
--------8<----------
where CleanExtraBullet() is the macro recording that Pierre suggested.
I am cleaning the source files of Getting Started 7.2
