Hi Johny, If this is indeed happening the way you describe it, that would be a bug. The 'label4=~".+"' selector definitely should match any series that have a value for label4.
What Prometheus version are you using, and could you file a bug report with more details (maybe a minimal reproducible test case?) at https://github.com/prometheus/prometheus/issues/new/choose?
