I have found a solution to the reported issue.

It seems that I have had the "Clean" mode box checked in the Notation Window. According to the User Guide, when Clean mode is set, the notation is automatically cleaned up, "eliminating the display of redundant grace notes and glitches".

With the Tick Offset set to Auto and the Clean mode box unchecked, the reported Issue does not appear; i.e., both Non-Editable and Editable notation of the triplet in question are displayed correctly.

It would seem that at least in this particular case, having the Clean notation box checked is not necessary or advised.

Regards, TS.
