Rule filters not working in OFI

Optimize for Infrastructure Administrator’s Guide Hi
I have encountered a problem with rule filters on OFI ( It doesn’t seem to work for custom dimensions.

I created an event map with one fact (errorCount) and a few dimensions (integrationName,…). I created two base rules for the KPI with the same expression (like errorCount > 5) but different rule filters (integrationName=”Test1” and integrationName=”Test2”).
When I run the addEvent ws with errorCount=10 and integrationName=”Test1” both rules are violated, instead of only the one with the right dimension filter.

Has anyone else succeeded with using custom dimensions as filters or is there any thing else I have missed?
