Hello to you GamePro1337,
California has a length rule which must not exceed 40 feet. This length is from the trailer kingpin to the center of the rearmost trailer axle.
Here is the California Department of Transportation
"Caltrans" website link showing the length rules:

Here is a website link from truckingtruth.com
"forum section where many experienced drivers share information" showing the 48 continuous states in regard to their length rule (kingpin setting):

In your example, it is clearly overexceeding 40 feet and this is why you got a fine at the inspection station. Thus, it is not a bug! Hope this help, Gabriel
