Renoise Note Off's filter? How to filter out Note Offs?

Maybe I don’t understand semantics of MIDI settings window…

I want to filter out the Note Off MIDI messages.

But regardless it’s ticked or unticked - the Note Offs get through.

I want Note Offs be ignored. I want just the Note Ons.

Context: I am routing Alesis SR-16 through U2Midi Pro Midi2USB cable. Unfortunately I can’t find options in Alesis to turn Note Offs Off.
