Chamfer favors one side of the edge when rounding

[dellmitch]

When I Chamfer an edge it always seems to pull one edge more than the other as shown in the picture provided. The only time it works correctly is when it's from a freshly created object. Once it gets modified, this is what I see.

-all of the modifier settings have been reset

-the object is quite simple

-I've tried messing with all the modifier settings

-I've tried resetting the object to Editable Poly and try again

-It's occurred over multiple projects

I tried recreating the object in your screenshot and performing the chamfer but it didn't bias it to any side. Could you share an archive of your scene (before the chamfer) for testing purposes? Also let us know what version of 3ds Max you are using.
