Why does the value of my block parameter change when I modify other parameters in my mask block dialog in Simulink 6.1 (R14SP1)?

I have a masked subsytem in Simulink 6.1 (R14SP1). I define several parameters for my masked subsystem, when I change the value of one parameter in the mask block dialog the value of another parameter is being changed. The mask parameters in question are:

 GAIN

 gain

 Ts

When I change my GAIN value, the gain value also changes.

This is intended behavior in Simulink 6.1 (R14SP1) when the variables names differ only in case, since Simulink is case insensitive when referring to variables.

To work around this issue, rename your mask variables such that they have different names.
