Speed Zones

Hey, I am having trouble with the updated school zone data

I contains same reference twice an example (there are more):
“SZ_ZONE_ID”: “29835”

OBJECTID/index 37 & 60
“SCL_NAME”: “URANQUINTY PUBLIC SCHOOL”,
vs
“SCL_NAME”: “COLLINGULLIE PUBLIC SCHOOL”,

Anyone I can talk to i.e. a bug you will fix or how to create stable key?

SZ_ZONE_ID - TfNSW identification of the Zone
