Is there an error in the example script in the "Constructing SISO models" entry in the documentation for Control System Toolbox 6.1 (R14SP1)?

In the DC Motor example under Help -> Control System Toolbox -> Getting Started -> Building Models -> Linear Models -> Constructing SISO Models, the units for the inertia J are listed as kg.m^2/s^2. I think they should be kg.m^2.

This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:
This has been verified as an error within the documentation for Control System Toolbox 6.1 (R14SP1) within the Constructing SISO Models section. The documentation should read as follows:
R= 2.0 % Ohms
L= 0.5 % Henrys
Km = .015 % torque constant
Kb = .015 % emf constant
Kf = 0.2 % Nms
J= 0.02 % kg.m^2
