Ad location templates
 

I've sorted out my styles into parent & child styles, eg:

-- Parent A
---- Child A1
---- Child A2
---- Child A3
---- Child A4
-- Parent B
---- Child B1
---- Child B2
---- Child B3

Editing the Ad location template for 'Parent A,' I am sure it used to update them in all child styles, however this is no longer the case. What am I doing wrong, or did it never do this?

Anyone know how to just edit two styles with ads (the parents) instead of all 9?
