Alain,
     I see the sample dataset you uploaded. 
     The version of the IDV you running has a bug of setting some variables 
contour default values, this is why you can not get the display. You can either 
upgrade the IDV to our nightly build release, or go change the contour setting 
for the variable you can not display. To do that, go Dashboard > Displays, 
select the data, and click the change button of Contour. The base contour 
should be 1, and also change the min/max value.
     The other problem is that the levels of the CAPE is being interpreted 
wrong, it should be in a 2D display, if you don't mind the vertical location of 
the display, you don't need to do anything, otherwise, you can use the Formulas 
> Grids > Make slice 2D to make the change.
