Same here. I'm using Xperia Z3 on Lollipop 5.0.2
Z3 display the first missed call as "received call as 0sec"
Z3 display the second missed call as "missed call"
when I called out to that number, next missed call from that number will be "The first missed call" and will be displayed as "Received call as 0sec"
Fix the bug pleaseeeee.
I have same problem with ZR after update. 
Sorry to hear that you have issues with missed calls. I will forward this internally for further investigation.
