Wrong speeds displayed in points' tooltips

I'm using uLogger to upload my positions on PhoneTrack and I noticed crazy speed values reported on tooltips (I'm not driving at 200kph in round-abouts...) I checked the data from the database and they are fine. Please have a look to the enclosed screenshots.

ISSUE: uLogger uploads speed in Km/hour, while Traccar uploads speed in m/second. uLogger values are 3.6x too high, as the database is in meters/sec uLogger(m/sec) = uLogger(kph)x1000/3600 = uLogger(kph)/3.6
