A shared ignition arrangement can produce sparks at multiple points. That pattern alone does not show that every burner has a separate fault.
What the observation means
The meaningful observation is whether the intended burner establishes and maintains a normal flame through the approved procedure. Persistent sparking after controls are released is a different issue.
A useful next step
Use the manual's ignition method and report the actual failed burner or ongoing clicking. Do not touch electrodes or remove hot burner parts during ignition. A gas smell requires emergency action rather than repeated attempts to determine which spark looks strongest.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
