Switch Log empty after power outage

Hello,
unfortunately I had to realize that the switch logs are empty after a power failure. Or the last entries are several weeks old (Power failure was on 17.01.25 the last log entries are from 06.12.24. I know for sure that there were log entries because I checked the log on a switch last week). Is this normal? How can I change this? This has happened with 8 pieces with the following Firmware 32.7.1.9-patch1-49 and models X440-G2-24T-G4, X460-G2-48T-10G4, 5420F-24T-4XE- Switch Engin

log settings:

This by design. Logs with severity Warning through Critical are retained after a power outage in the nvram which you can see with below command.
