Notification issue with admin role

Decided to test enterprise version, it seems admins dont receive a project notifications for some reason. Is this a bug?

By default, admin receives nothing. Starts receiving when admin becomes a project participant. If translated something there, then receives as a translator. If added into project as a manager - then managers notification (source stings updates and so on).

Receiving all notifications by default = tons of notification in case organisation is really big, so this is more a feature.
