Former login deleted from the Recent Logins list when disconnected

SYSTEM INFORMATION
OS type and version Ubuntu Linux 24.04.3
Webmin version 2.520
Virtualmin version 7.50.0 GPL

I log into Virtualmin from several different IPs and sometimes does not log out.
When logging in again from another IP, I look at the Recent Logins list and press the disconnect button for the previous connected login.
When I do so, the now disconnected login is deleted completely from the list. The line is missing and does not appear in the recent logins list anymore.

The whole thing looks to be a bit of a mess. I have logins that have timed out that show under state as’ logged in’ but they don’t show up on the current login page. Under current login page I hit a button to ‘show all’ and the only thing that happened is the button disappeared.
