Issue 1:
When I draw a new zone in my job, OptiSurface will often merge 2 zone together. It seems to merge zone more often when I am working with Valley or Ridge.

Issue 2:
I try to create a new zone, it merges with an old one. Could you please let me know what I do wrong?

Solution for Both:
This is a bug we have discovered recently. We think it happens when subzones names are modified and or they are deleted. We believe we have fixed this in V1.4 which we hope to release in next couple of weeks.

Work around is don't change the name of subzone and try not to delete any subzones. Modify the extents instead. This problem only happens rarely.
