All burners ignitors click/spark after burner turned off

After using one of the cooktop burners and then turning off the burner, all burners continue to click/spark for about 15 minutes then stop. The only happens with when I use one of the burners. Any suggestions on what I should try replacing first? Spark electrodes or spark module? Or is this a grounding issue?

Thanks,
David
