The Unknown segments are in fact car segments. The Bike segment is a mistake. No Data segments should be joined with places (Custom place). The walking segments are spot on. Geofence and Wifi over GPS were turned on.

reprocessed, both recognized as car segments. There are 2 problems that remain. Walk is noise there and DBScan didn't catch that also bus segment should be car.

Ok I found little fix for dbScan for representative cluster. so now there is no walk noise.

For bus problem (little segment), it's ML problem, needs better interpretation.

As for no data - static - no data: it's dangerous to merge on backend (you could have turned off phone and traveled then hit static for example so this should be done on web by user.

Thanks for reporting Alex.
