Filters currently enforce uniqueness in almost all cases. So I am not sure if this has a solution other than updating the filters.js tiddler.
I think in some cases if the filter operator doesn't explicitly remove duplicates and is the last in a filter run it may return duplicates, but I don't remember the specific circumstances where I got that to work so I may be misremembering. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
