Log File Monitoring Problem

I'm monitoring a logfile for "Incompatible Types" error.

However, recently, one of the log files came up with the error,

and Hobbit didn't detect it. Here's what I'm looking for:

(Note: Code can be different)

CWWBE0085E: Incompatible types

This is what my log description looks like:

LOG /opt/log/SystemOut.log %J2CA0056I|J2CA0020E|Incompatible Types|Assertion COLOR=RED

Does it have to be lower case? Incompatible types

Thanks.James
