"Stop after" not shown in the Info-Page

Hi,

i have configured alerts in hobbit-alerts.cfg:

HOST=%.* MAIL recipient (at) company.examle DURATION>3 DURATION<10 REPEAT=1

This works fine. Hobbit sent me 7 mails after 3 minutes each minute and after that no more.

But i can't see anything in the "Stop after" column in the info-page.

Any help?

Alex
