Interpolation Corine Land Cover on an input mesh which has already a variable Bottom interpolated : style not well applied

@jean-marie.kerloch I take as input mesh a mesh already interpolated on a point Cloud for the variable BOTTOM.
I do the interpolation with Corine Land Cover.
The mesh have 2 variables : BOTTOM and BOTTOM FRICTION.
But the legend with style of Bottom friction seems to be applied on the variable Bottom. The values of Bottom seems to be always valeus of bottom.
Values of variable Bottom Friction ok but legend and style of bottom friction not applied to this variable.
By default, this style for bottom friction if ther are two variables in the mesh file.
