Ah I see.  yeah right now the only way to remove is to simply close the note, else it needs to  be reported (only under dire circumstances).

if it's a 4 way stop it should be both directions.  this was meant for if two streets of different hierarchy intersect like a secondary intersecting with a residential, normally the secondary doesn't need to stop.  also if there are two equal hierarchy intersect or some other circumstance some people don't need to stop, that's what all the options are for.
unfortunately sometimes it's hard to get it to make a stop point in exactly the ways it needs to, then people just put them on the road and make sure it's pointing in only the direction that makes sense...

so it is a bit tricky sometimes, though i think in this case a 4 way, it's fine.
