I think I have discovered a wee glitch. I also want to call into question two other default behavior and you can educate me if they are correct (they very well may be and I just don’t know it.)
I decided to do my own engraving or an organ toccata by Denis Bédard so I could format it onto 11x17 paper to make easier page turns. At the very end of the work, there are long sustained dotted whole notes tied together with dotted half and dotted whole notes punctuating the middle voices.
Image 1 shows the final chord. The Low/High 'F’s are in voice 1, while the A & C are in voice 2. By default, they display out of alignment which strikes me as odd as these are stemless notes in 3rds which should align as a neat chord.
(As an aside, I’ve also placed a box around two chords. I’m wondering why Dorico decides to put one on the left and another on the right?)
In an effort to fix the alignment of the final chord, I forced the A&C into voice column 0. This produces the desired alignment HOWEVER, Dorico mysteriously drops the dots from the A.
(As a second aside, I’m also curious why, as shown in image 2, the dots are aligned for one chord and not for the other.)
Ignoring my two tangential points, it does seem that there is a glitch causing some dots to disappear after changing the voice column, even if the default alignment is correct.
