Possible bug in Diagnostic Viewer for a switch block

Hello,

I was experimenting with the Switch block, trying to select one or another vector simultaneously for different cases. Since I wasn't being able to, I decided to open a blank new Simulink model, to try it in a simpler way.

When I was trying it, I arrived to the situation in the attached file, that, if you run it, it outputs an error. In the Diagnostic Viewer you get the follwoing message:

% The signal dimensions of the first and third input ports of Switch block 'deleteme/Switch' are
% different. To support a variable-size output signal, on the "Signal Attributes" pane of the block
% dialog, select the parameter "Allow different data input sizes (Results in variable-size output
% signal)".

Well, this is obviously not the case. The dimensions of the first and third input ports are the same.

Instead of giving array value give scalar value to the switch control input that will not through you the error.
