I believe bug in user preferences

[Ricsca]

If I try to change the user's preferences in administration, only those relating to the signature are saved.

Even if you select:

Receive news and update emails
Receive activity summary email
Receive email when a new conversation message is received

They are not saved in forntend.

Can you confirm that the 2 screens I attach concern the same preferences but one is the preference that the user sets while the other is the preferences that the administrator can set for the user?
