How long stale metics are keeping in index?

Hi All,
Today I noticed that some stale metric is visible on 7 days graph, but 30 days graph said "No data". I did some queries and dound out that metric is visible until 13 days and 4 hours from time when block with metric was flushed.
Is it intended? I can't find such odd time in config.

Nevermind. It was not Mimir's fault, but Grafana's maxDataPoints 🤦
