Simulink 'To Workspace' block inactivated when additional simulation parameters are provided

I have a Simulink model with a 'To Workspace' function block for trouble-shooting purposes.

If I type

sim('MyModel.slx')

data is loaded into the workpace.

If I type

sim('MyModel.slx', 'StartTime', '0')

no data is loaded. The default start time is also 0.

Is this a bug, a feature or a known limitation?

I have noticed a similar issue using simstate. see the link.

This appears to be a feature.

If you look at the link, you will see that all you have to do is set parameter values using "set_param" before running with "sim".
