Group access level Elgg on 1.7.5

Hi all,

I've installed the version 1.7.5 of Elgg, and I'm happy to see that, when I want to publish a new wiki page for example, I have the list of the groups I belong to in the access level dropdown list. But, unfortunately when I save my wiki page, this doesn't save the page in the group I want the page to be in.

Does anyone already fix this bug ?
