That's because the walking trail and street have been wrongly connected together. Disconnecting the two will prevent waze from directing drivers onto a non-drivable road.

Waze will have a few jittery problems, throw up its imaginary arms and have a full scale toddler tantrum at the walking trail connected to a street! Better all round if the two types are disconnected.

Also waze users driving in the area without a "route" typed into the app will not be tricked into taking a seemingly quicker route only to discover it's not a road at all (bit like being told to turn left onto a railway line )

This that simple! I am a bit surpised that Waze is not taking into account the nature of the road !!
