IP Notify profile not defined message in System Messages

Every time my M15 boots up I see the follwing message in the System Messages list:

19:35:23 BOOT timetasks[1088] IP Notify profile ‘ip_5389bfa7’ not defined or IP Notify not available.
19:35:23 BOOT timetasks[1088] IP Notify profile ‘ip_5389c11b’ not defined or IP Notify not available.

In the .cfg file I see:

SECTION timetasks
CRON=/1:::::IPNOTIFY-ip_5389bfa7:
CRON=
/1:::::IPNOTIFY-ip_5389c11b:
ENDSECTION timetasks

Can I just remove those 2 CRON lines (leftovers?) or do they have a specific function?
