Entering multi-rhythmic parts on drum kit line

[Musicalnut2004]

Trying to input this line. When I add the triplet to the snare/toms, Dorico is changing the values of the snare/toms and adding the triplet to the kick. I’ve tried switching voices, adding extra up stem voice and nothing seems to work. I’m sure I’m missing a simple step. Help!

Try changing you percussion kit layout temporarily to single-line instruments and adding the triplet there. Keep the BD in a different voice.
