If you want the three notes to be beamed together, you must either:
Show all instruments in the same voice (probably not what you want?)
Notation Options > Percussion
Or, if you choose the other option (Use voicing defined in kit editor), then you’ll need to edit your percussion kit so the two instruments corresponding to the E and the D in treble clef (maybe toms 2 & 3?) have the same voice as the one correponding to the A (Crash Cymbal 2?)
