Data jsons Fail Validation

All of these Data/jsons failed validation for me:

blackGoldIsland
busStopGarage
cargo_1
fishermansRetreat
highHouse
hqmQuarryRuins
observationTower
oilPlatform
pirs
rustedDam
rustedGates
strandedBarge
submarine_1
teslaGenerator

I didn't quite understand what that meant.

When I tried to open any of those they all failed with an error. When I ran them through this js0n validator it confirmed the error:

They're not meant to be edited, so I guess it doesn't matter. If that's important to you, then use Notepad++.

Changed Status from Pending to Closed

If you are saying that errors in the data files are not impacting the functioning of the plugin then I will accept that but it sure seems odd to me
