Strange voice navigation behavior/cut out

if there's is a camera alert just before your next turn, Serena will start to talk "in 400 ....", then it gets cut out by camera alert sound, then it repeats last sentence "in 400m turn left", but obviously it's already too late, it's quite annoying actually. It has happened several times while I was driving through Bratislava and Brno.
I also have standalone TomTom 6200 and it didn't behave like that.
