I understand what you're getting at now. With an event day sign right by the sign for one of the zones, but with no applicable zones on it, it could be considered confusing if you then pass a sign for another zone with no event day sign. You could be mislead into thinking there were no restrictions for that zone.
So if you want to take this further, you'll have to wait for the Notice to Owner and submit a formal representation on the above lines. Note that whilst the discount option is lost, they normally re-offer it when rejecting reps, although there is no guarantee on this.
Others may wish to comment so do wait a bit.
