The reason the tuplet is up, is that — in the actual music, there is a lower voice, so the tuplet *has to be* up. I left out the lower voice in my example, because it is not relevant to the behavior I am asking about.
In the real score, I have not overridden the tuplet and slur direction. With the lower voice present, LP automatically puts the slur and tuplet bracket "up", with the "crashing" behavior I showed.
