last box did not plot correctly. Thanks

[j0hnCathey]

I can't send any data. The code is just the code for a boxplot with two groups. The first three plotted fine, but the last only shows what appears to be a median value but it's not the actual median. I'm attaching the 12 values that comprise the variable in the monoplegic box plot and the plot itself.

Any idea on why that last box on the right plotted like that. The the summary for the y axis is summary(A0272t$EMTattrigger)
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max.
  8.000   8.550   9.400   9.767   9.950  16.000
