Error 404 page

Hi guys,

When entering a group the BP Group Email settings clutter the front page of the group. These options show there even though I have not clicked on the change button.
Besides this, when clicking on one of the options it just takes me to a 404 page.
The options are:

No Email I will read this group on the web
Weekly Summary Get a summary of topics each Thursday
Daily Digest Get the day’s activity bundled into one email
All Email Send all group activity as it arrives

I’d appreciate any help.

Thanks.
