Problem MadCam5 Box-region Problems

Hello,
first sorry for my bad english.

I try MadCam5 since some Days.
No i saw an little Problem.

Did you see that in MadCam 5 the enclose or enlarge Box by Cutter Option won't work correct.
If i use the automatic size for the Box the Program don't set the comma (Point) in the Size Number. So the Box is much to big.

Is this an mistake in the Program, or did i make something wrong?

Here my PC Data. Maby the Problem is because i use an Apple iMac27 i5 with Paralells Desktop and Windows8 64bit.
Rhino5 and MadCam5 normally works fine. Only the Box Dimensions won´t work.

Regard´s ,
CME
