Why does the scale of buildings change when exporting from RoadRunner to Unreal Engine?

When I export a building from RoadRunner to UnrealEngine, its scale somehow changes.

For example, a building which scale is x=1,y=3,z=2 in RoadRunner is distorted in UnrealEngine as shown in the  screenshot below.

If the scales x,y,z are equal, this phenomenon doesn't happen.

How can I avoid this issue?

Unreal Engine 4 does not handle rotation and scaling very well.

A workaround is to freeze the transforms in something like Maya before importing into RoadRunner.
