The cookware and zone sizes are mismatched. Energy can be delivered outside the useful base area, and the arrangement may not follow the hob's recommended use.
What the observation means
For induction, the same mismatch can instead cause recognition problems. Technology therefore matters when describing the result.
A useful next step
Choose a zone suited to the pan under the manufacturer's guidance. Keep handles clear of neighbouring heat. If an appropriately matched pan still performs unusually, report that comparison. Do not solve the mismatch by placing an unapproved metal plate beneath it.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
