Bus array across model boundaries

I'm attempting to send a bus array across model boundaries, but Simulink throws an error complaining that the port dimensions do not match. The input port of the referenced model is set to accept the bus type and is configured to inherit dimensions. I've attached an example model which shows the behavior.
I have gone through the Simulink help which describes using an array of busses (https://www.mathworks.com/help/simulink/ug/combining-buses-into-an-array-of-buses.html) and it does indicate that one of the benefits is using busses across model boundaries. Unfortunately, I wasn't able to locate an example file which showed the implementation and ran in to the problem above.
Any help is greatly appreciated!

Hi Allen, if you set the port dimension of input (Request<DriveLimit>) to be 3 to reflect the three buses in the array of buses, the problem is solved. There is an example similar to your model that you can take a look at https://www.mathworks.com/help/simulink/ug/importing-structures-of-matlab-timeseries-objects-for-bus-signals-to-a-root-level-input-port.html
