distance from ground - zone in PVsyst shading scene

[PVsystUser]

I changed this number to different values ( 0.5, 2m, 30m) and it seems it is not reflected anywhere. at least when having multiple zones with different distance from ground , they all look to at the same heigh :

Hello,

I did a similar test in version 8.0.18 and is seems to work as it should on my side. The zone to the left is places 0.5m above the ground the the zone to the right 5m above the ground. 

If the issue persist, please describe further how to reproduce it.

Kind regards,

[PVsystUser]

My PVsyst version is 7.2.16.

Please update to the newest version

If you must stay at version 7, you can mark all the tables and move the selection using the arrow, or define the height in the tools section:

I am adding this question under this thread as it might be a version-related issue similar to the above issue.
I have two projects that are the same except for the shading layout. I see ~2% difference in the near shading loss (4.5% vs. 6.7%), which does not make sense for not such a big difference in their layout. 
The site is flat, and the module is First Solar so no backtracking. We have removed the trees, and the result didn't change.
Could you please give us some idea of what we can check to nail down the source of the issue?
We can't share the logs.
