Access https://meta.wikimedia.org/wiki/Special:AbuseFilter/test and copy a filter to test over there. Then check the "Show changes that do not match the filter" checkbox and next click "Test".
The icons that say us if an edit triggers the filter or not do overlap with the edits. That didn't happened in the past.
