Vertical Mapper .grc value wrong

[tavakian]

I have an .mrr file that I'm converting to a VerticalMapper Classified Grid .grc file in MapInfo. When I load the converted .grc file in Alteryx, the values are not matching up with the polygons. After further investigation, Alteryx is shifting the indexed value by 1. This is causing the Map in Alteryx to show the previous value for each polygon.

Is there a work-around for this? I'm currently using version 2020.2.3.27789

Thanks,

Tom

Any chance you can share the file or a sample of it so we can do a little hands on testing?
