So "living zone" in Latvia is the signed "dzīvojamā zona" (20 speed limit, pedestrian priority, etc.) On OSM these are tagged as living streets (highway=living_street). The speed limit there is always maxspeed=20.

In this case, the roads were tagged as living streets since they were drawn. Then you added 50 speed limit to them, which means either the speed limit was incorrect or the living zone designation was incorrect. I understand now there is no living zone here, so the designation was incorrect.

I have already changed these to regular residential roads since then based on available footage of the area. I added back the 50 limit too now.
