Auth. Status Enable Checkbox cleared when saving Roundcube settings

[valo-lindstroem]

I'm having the problem that the "Enable Auth. Status Column" checkbox is cleared whenever i change and save default roundcube settings, e.g. i change a special folder and save that then the checkbox is cleared and i have to set it again.

Thats ok for me as the admin to enable it again after saving my settings but i'd like my users have the column displayed by default and not losing that settings when changing settings.
