Symbols disappear if moved a few spaces
2.0.3 on Win7 / 2.0.2 on Win 10
See attached score. Select the right-parenthesis in measure 7, enter edit mode (Ctrl + E), and move it 1sp at a time to the right (Ctrl + right arrow). After about 4 spaces it disappears completely! Put a pair of notehead brackets (noteheads palette) wherever you like and repeat the experiment: the right bracket always disappears after you move it a few spaces to the right.
