Missing number in Nashville number for score created from jazz template
1) new score from jazz lead sheet template
2) select first rest
3) Add / Text / Nashville Number
4) type "1m"
5) press Esc
Result: the 1 disappears. It's still there internally but somehow the rendering goes wrong, probably an issue managing the tpc or with the render root rule. I can reproduce also in the default score after changing to jazz chord symbol style, but only after save/reload. Still investigating. Not a regression - same in 3.4.2.
