It's normal behaviour. Dot appear only after some amount of time and/or if there many unread notifications.
If you wish immediate notification you may install Notifications Alert extension - https://extensions.gnome.org/extension/258/notifications- alert-on-user-menu/ -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1559491 Title: Unread notifications dot mostly never appears, even when it should Status in Ubuntu GNOME: New Status in gnome-shell package in Ubuntu: Confirmed Bug description: When a desktop notification comes up and one ignores it it goes into the little area for previous notifications next to the calendar. A little dot should also appear when you have unread notifications in that section, the dot should appear on the right of the date and time at the top. However I have found the behaviour of this dot to be inconsistent on Ubuntu GNOME 15.10 with GNOME 3.18, sometimes it does show when there are unread notifications, 98% of the time it does not though. I have also tested Ubuntu GNOME 16.04 with both GNOME 3.18 and 3.19 and found the issue also to be present there.
