@MichaHoffmann, can you tell how can I export blocks from Prometheus & Thanos Store please? Thanos Query args: ``` --log.format=json --http-address=0.0.0.0:19192 --query.auto-downsampling --query.partial-response --query.max-concurrent=20 --query.replica-label=thanos_ruler_replica --query.timeout=180s --query.replica-label=replica --endpoint=dnssrv+_grpc._tcp.thanos-store-api.prometheus.svc --alert.query-url=https://thanos-query.domain.com --enable-feature=query-pushdown...

Update: The issue disappears when all the Vector Agent pods were restarted. I still don't know why the buffer metrics were negative in the first place.
