fluorLegend not working when fluor targets aren't unique

[mgrout81]

I am using mu_dev_E9_003 in SOO and trying to run plotSpatialOverlay() with fluorLegend=TRUE. I get this error:

Error in `[[<-.data.frame`(`*tmp*`, i, value = c(DNA = "#0000FF", Custom = "#00FFFF",  : 
  replacement has 4 rows, data has 2

I believe what is likely happening is that the code is assuming unique Target values for all rows, but I only have 2, "DNA", and "Custom":

I assume "Custom" indicates a lack of something in particular specified by the user on the DSP instrument, so likely this is something that will not be too uncommon.
