Hi Martijn,
If you changed a file in the past this might cause the issue because if you change definitions from the files it will override SmartConsole settings.
I would check if you have the following file: $FWDIR/conf/log_policy_extended.C . If so, you can try to change the name and re-install DB on CMA. (mv $FWDIR/conf/log_policy_extended.C $FWDIR/conf/log_policy_extended.C.ORIG )
You can verify what are the definitions loaded to the CMA by looking at fwd.elg of that CMA, look for difference between "loaded set" which is what the definitions try to load and "working set" are the definitions that actually gets enforced.
I think this will help you solve the issue or lead you in the right way.
Kind regards, Amir Senn
