Format -> Style… -> Tuplets

4 types of issues

1) Use of “the” in strings is incorrect. The normal convention is not to use “the” in strings e.g. the following strings should have all “the”s removed:

Vertical Distance from the Notes
Avoid the staves
Horizontal Distance from the Notes
Distance before the stem of the first note
Distance before the head of the first note
Distance after the stem of the last note
Distance after the head of the last note

Should be

Vertical Distance from Notes
Avoid staves
Horizontal Distance from Notes
Distance before stem of first note
Distance before head of first note
Distance after stem of last note
Distance after head of last note

2) Strings Auto and Automatic are used. No reason to mix. I would suggest using
Auto for both if space (dialog width) is an issue
Automatic for both if it is not

3) Number type and Bracket type have as an option in the drop-down menu, “Nothing”. Should be “None”

4) Strings are right-aligned or centered.
Should be left-aligned like all other strings in this dialog.
