It seems that line sensor can detect maximally 10 entities. It reports more, but they are not accessible through UAQ.
Documentation ReferenceManual.pdf says:
26.14.7 Line Sensor
<preQ> := Sensor.Line..LLines. or Sensor.Line..RLines.
<preC> := LineSensor[].LLines.L[] or LineSensor[].RLines.L[]
with i=1…100 (1 is the nearest line) for and i=0…99 for <preC>
So I expect that line 11 could be normally accessible when sensor reports 11 detected lines…
