RAXE500 email router logs daily/hourly not working

My email in advanced - security - email  is configured properly  with "daily" and "12:00 pm" set

In administration  - logs,  I can send logs through email by clicking the "send logs" button. (a log entry is created)

The issue is that I never see the logs sent at the scheduled specified time (or any time)  It only works manually on demand 

What is needed to activate scheduling to have logs sent automatically?

 Firmware Version V1.0.1.52_2.0.34
