Warning = no fine, no punishment other than the officers words = no points.
It bothers me slightly that you aren't able to understand the concept of a "warning", but are operating a vehicle.
The letter is likely due to the previous offence.
If the ticket wasn't being given as a warning, the extra "t" wouldn't make a difference.
