Speed limit data is from a service not inherent to the map data. The service is the most accurate when path data is used.
Getting the speed limit based of individual road segments from a vehicle that isn't snapped to a route can be spotty at best. Any latency in the service makes it that much worse.
A lot of navigation apps will take the better safe than sorry approach and just not display the speed limit in this case.
