Nitpick time. The map with columns needs to define clearly which part of the feature is impassible column and which is base which could be moved over (with perhaps a -1MC modifer).
Also, all standard battleground maps are 36 by 30, which is a 5-to-6 ratio base to height. Your maps are very slightly off this ratio.
Yeah, these are just the bare maps with out the scenario defined special rules.
When I draw them in CC3 they are 36X30. I don't know why they are different here.
I've got a quick sec, I'll try and post another one.
