Why Grafana Loki does not persist old logs?

I'm locally running Docker containers grafana/loki:3.4.2 + grafana/alloy:latest. I'm trying to upload 50 hours old logs into Loki in order to run some tests. However, Loki does not seem to persist any of these old logs (it does persist logs newer than 24 hours). Is there any way to upload old logs into Loki and query them?

Timestamp parsing in Grafana Alloy seems correct during live debugging. Grafana Loki successfully receives logs from Alloy ("push request parsed" message is present in Loki's logs).

GET http://localhost:3100/loki/api/v1/labels returns labels correctly. GET http://localhost:3100/loki/api/v1/series return empty response.

Adding this section to Loki configuration solved the issue:
