IPS Not Working (UTM 9)

Has anyone experienced any issues with IPS on UTM 9?

It looks like it is configured correctly and listening on my internal LAN, yet IPS never caught a single entry… even simulating i.e ping -s 666 and IDSwakeup etc do not yield any response/acknowledgment/ IPS log entry.

The only IPS log entries are:

Am I missing anything?
