Prometheus added labels are not exported to stackdriver

Hi all,

Could you please explain or advice, why additional labels added by Prometheus are not exported to GCP/stackdriver ?
My assumption this is due to WAL updates processed by sidecar before Prometheus add its own labels.

Well, it seems that metrics with labels transferred to stackdriver, but in Metrics Explorer's labels filter it doesn't appear.
