On pages which are either a forum container, or a forum index that lists all the topics in a forum, custom page titles do not work at all.

Instead the default forum page title is used on all of them.

ege assuming this structure:

Forum Index
- Container1
-- Forum1
--- Topic1
--- Topic2
--- Topic3

Forum Index, Container1 and Forum1 all have the same page title. Container1 and Forum1 should have different titles to Forum Index.
The page titles on topic nodes work fine.

I have tried setting a pattern in the forums vocab box on page title settings. This is ignored.
I have tried setting an individual title on the settings page of the forum terms themselves. These are ignored too.

I am using advanced forum in conjunction with core forum if that makes a difference.
