GE Profile cooktop ignition problem

[blwn31]

Hey guys, been a while since I posted. Hope all are well.
Anyway, my GE Profile Gas Cooktop JGP962SEC2SS has one burner that will not start the ignitor. Last week when my wife went to cook something, the ignitors wouldn't shut off. So I had her unplug the cooktop. Now, we have one that won't start the ignitor. We have to turn one of the other burners to the light position to get the ignitor to fire, since they all fire if one is on (normal ops). Question is, have you all seen this, and is it an ignitor module issue or an individual control valve issue related to the said burner? Any help would be appreciated.

If one will ignite then you can be sure the spark module is fine so you must have a bad spark switch.
