Losing recent data when restarting Prometheus service

I think I’ve found the cause of the problem. The command sudo ls -lh /var/lib/prometheus/metrics2/wal/ showed two directories: checkpoint.00001219 - current checkpoint.00016128 - old. After deleting checkpoint.00016128, the service restarted correctly. WAL does not check for additional checkpoints, which prevents it from working correctly when the service is restarted.
