My initial thought is that your left hand switchgear could be defective. Following water ingress problems, most early model bikes will have had the handlebar switchgear replaced, probably both sides, under warranty way back.
Your dealer should be well acquainted with the issue & can easily check your bike's history to clarify.
BTW, welcome along to the group - give us an intro, when you have a moment.
