SOURCE: igniters are not working right

when you turn any burner control to lite all ignitors should click this is normal industry wide. the ignitors are controlled by switches that are placed over the valve shafts they are wired up together so thats why they all click when you only operate one valve don't worry about it. the ignitor stays on untill you back the valve off a tad this is also normal.

SOURCE: Clicking noise on cooktop even when all burners ignite

I have a viking gas cooktop. The ignitor on one of my front burners wouldn't stop clicking even after the flame ignited. I swapped that ignitor with the ignitor from a back burner, expecting that the problem was with the ignitor and that the back burner would start to click incessantly, but at least I'd have my favorite front burner for use. Instead, the front burner was then only clicking 50% of the time and the back burner was fine, suggesting the problem was related to the burner not the ignitor. I pulled the front ignitor a bit away from the burner and now it is working normally. Hope this helps.

SOURCE: exhaust fan comes on when burner turned on

The left side is set for your grill. There is apparently a switch under the left side top / front of the cooktop. The aeration tray has a prong on one end that fits into a hole in the front end of the burner basin and activates the switch which stops the fan from coming on when using the burners and allows the fan to run when using the grill. Try switching sides with the aeration trays as one might make better contact than the other.
