Collision Size Problems

I am using the UMSWE 4.1 editor and am having troble making the collision sizes work properly. When I change the collision size of a unit it seams to only affect units attacking it but if a unit is just moving the new collision size isnt applyed and it walks right through the model!
Is this normal or is my WE messed up, casue it kinda sucks making big units that smaller units walk right through.

There's another value called pathing size, I think that's the one to edit.
And no, this issue is not UMSWE related.

That is 1 Pathing value i do not have :/. I have 3 unit pathing values whitch are -- AI Placement Radius, AI Placement Type, and Collision Size. None of these work. The scale model size in the art section makes the model bigger but doesnt change the pathing.

I am using a custom model (the Ancient Dragon Lord) from the download section here and used the Granite Golem for my base, but I don't think this would be a problem. Any ways, a bit more info on the Pathing - Size value would be of help.

Alright the UMSWE and WE Unlimted both have the same 3 values for pathing. Also the normal editor has the same problem so its defiently some kind a bug. Some 1 else try to get this to work plz: change the collision size of a unit so it affects both attacking AND moving.
