Webmin doesnt recognize the new System Version

[corin.corvus]

SYSTEM INFORMATION
OS type and version	Debian 12
Webmin version	2.303

Hey,

i installed Webmin yesterday on some Debian 11 Servers and after that i upgraded them to debian 12.
Usually Webmin recognizes, that Debian is now on a new version and update the Number in webmin, but this doesnt happen.
After manually change in webmin config to 12, webmin means, its still debian 11.

i restarted webmin, the server, reinstalled webmin, nothing worked.

how can i solve it?

Thanks
