FreeNAS sending alert mails although alert frequency is set to “never”

In FreeNAS 11.3-U2 I have set:

Code:

  System → Alert Settings → Scrub Finished → Set Frequency: NEVER
  System → Alert Settings → Scrub Started → Set Frequency: NEVER
  System → Alert Settings → Replication Succeeded → Set Frequency: NEVER

When I click alerts (the bell icon) is still shows the alerts:

Code:

INFO
Replication "tank/foo" succeeded.
…

INFO
Replication "tank/bar" succeeded.
…

INFO
Scrub of pool 'freenas-boot' finished.
…

INFO
Scrub of pool 'freenas-boot' started.
…

WARNING
Certificate 'freenas-pre-certui' is expiring within -2261 days.
…

And every day I receive several status emails from freenas:

Code:

Current alerts:
* Device: /dev/ada1, 1 Currently unreadable (pending) sectors.
* Device: /dev/ada1, new Self-Test Log error at hour timestamp 47042.
* Scrub of pool 'freenas-boot' started.
* Scrub of pool 'freenas-boot' finished.
* Certificate 'freenas-pre-certui' is expiring within -2261 days.
* Replication "tank/foo" succeeded.
* Replication "tank/bar" succeeded.
…

The unreadable sector notice is the one I want to receive. But why does freenas display the scrub and replication alerts in the alert menu (bell icon) as well as the notifications via email although the frequency is set to NEVER?

Is this working as intended? If yes, how can I configure freenas to not send emails notifying about scrubs and succeeded replications? I would like to only receive emails about things requiring attention.
