Aster Plot visulization went wrong

Hi, 

I am using Aster Plot whiling discovering the width visualization error. I used the first variable "VALUE" to control the depth, and the second variable "WEIGHT", which is fixed and very small (close to e-15), to control the length/angle, so the data label would be the same as "VALUE".

However, the depth/color/categorization/outline turned out to be quite strange in some cases occasionally (E.g. salient is the smallest in number, but has the largest depth, or maybe it's actually not salient at all...). Could anyone help on this? Thank you!
