Invalid Simulink object name when building a subsystem for PIL

I was trying to build a statemachine subsytem and plan to do PIL verification to it. I did the procedure indicated on this site: https://blogs.mathworks.com/simulink/2011/03/29/invalid-simulink-object-name/ and the results shows that mychecks for blocknames have passed.

Still I keep getting the same errors.

Any clue on what is causing this issues?

Hello Renan,

The Simulink Check rule you run is a check on subsystem naming rules.

On the other hand, the error message does not appear to be a naming rule error. Can you attach a model that causes the error?
