Can you double check the Card list definition? Both in Subject > Settings: Card list form-group, and Subjects > Components > Card list
Maybe all columns are Hidden, either in the model or due to rights. Just want to make sure it isn't the case here.
For as far as I can see the Card list should be compatible with the HTML control.
