Z17 mini (NX569H) not showing missed calls notification

Bug description: Z17 mini not showing missed call notification. When I go to “missed calls” section of dialler, it is always empty. I tried calling both sim cards, from various numbers.

Affected version: MK71.2-nx569j-201801291655-NIGHTLY.zip

Steps to replicate: miss a call?

I checked more closely, and all the missed calls show under “incoming calls” with duration 0 seconds.
I appreciate help with this issue…
