Blocker Description
Below is from list.
You're doing nothing wrong.
The filters as written recurse until they find a match. If long stretches between matching rows, then you will get a StackOverflowError. Filters need to be changed. Thanks for pointing this out. Can you do without them for the moment until we get a chance to fix it?
