the FilterHandler.java L184-186

            if (filterDuplicate(position, preceding)) {
            filterType.append("Duplicate ");
        }

should be

            if (filterDuplicate(position, preceding) && !skipAttributes(position))) {
            filterType.append("Duplicate ");
        }

Looks like this one ')' extra.

should be....

if (filterDuplicate(position, preceding) && !skipAttributes(position)) {
        filterType.append("Duplicate ");
    }

this change need to be considered back in the next release
