Score display does not respond to unchecking of "Begin/Continue/End text" boxes
Steps to reproduce issue:
1) Place a "Line" (any element from the "Lines" palette that contains text) over any section of the score.
2) Check or uncheck any of the boxes that control the text (e.g. Begin Text, Continue Text, or End Text).
The element's text does not change, and when deselecting and selecting the element, the text settings have been reset.
The workaround I've discovered is just deleting whatever's in the "Text:" box (e.g. for an 8va, deleting the "ottava").
