After updating the durable consumer information of a stream, the sum of these metric is increased

[xuanlinhha]

• I have a 3 nodes cluster nats server & I monitor the number of un-processed messages on some jetstreams to do some scaling. But whenener I update the information of the consumer of 1 stream, this metric increases by a very high value although there is no message at that time at all.
  The information of the consumer I updated is something like ack_wait, max_deliver. This doesn't happen with 1 node nats server.

This is the metric I monitor:
sum(jetstream_consumer_num_pending{stream_name=~"some-stream*",consumer_name=~"some-durable-consumer*"})
+
sum(jetstream_consumer_num_ack_pending{stream_name=~"some-stream*",consumer_name=~"some-durable-consumer*"})
