Indicator Glyphs

I have a SpanIndicator spanning multiple lines with a glyph. If I also assign a LineIndicator (also with a glyph) to each line of the span, the SpanIndicator glyph shows up on every line of the span rather than the LineIndicator glyphs. The SpanIndicator priority is 50, the LineIndicator priority is 1.

I would expect the SpanIndicator to be on the first line, and the LineIndicators thereafter. Why is the SpanIndicator replicating?
