The forte interrupting the continuity of the bar line caused it's two parts to be recognized as a flat and arpeggio.

The distance from the bottom of the upper bar line (y=794) to the top of the lower bar line (y=866) is 72 pixels. BarsRetriever maxBarCoordGap defaults to 2. The maxBarCoordGap is a ratio relative to the Interline value (thickness of one staff + space between staff line). Example random sampling of Interline: 662-635 = 28. So 28 * 2 = 56. Hence, the gap is too large for the two bars pieces and therefore they are discarded from consideration. I had a mine set for 4.0, or 108 pixels which should have been sufficient. Does the intervening run from the forte interfere with a gap analysis?

top bar line:
height: 794-579 = 215
extension below staff line #5: 794 - 692 = 102

bottom bar line:
height: 1015 -866 = 149
extension above staff line #1: 903 - 866 = 37

gap: 866 - 794 = 72
