Search Mail Log missigng from Logs and Reports

Hi, I am using Virtualmin with Webmin version 1.782 with Authentic Theme 17.70 and in Logs and Reports (in Virtualmin) I am missing the option Search Mail Log.

How can I make it available (I am logged as root) ?

Also, on the system information page I am also missing Virtualmin version (I saw some print screens on the net where this info is present).

Thank you,

Kind regards,
