Same issue here.
The log shows my last received call was Monday, but I know I received at least one call Wednesday and two today that I answered.
There has also been at least a couple of received calls this week that Nomorobo picked up (I assume) that aren't showing up either. Those don't get logged in my phones caller ID memory (never have, Nomorobo picks them up too fast, I guess) so I don't have a record of exactly when they came in, but I've definitely heard the phone ring it's characteristic 1 ring then go silent.
Placed/outgoing calls seem to be getting logged correctly.
