Gremlins 2 WGA writing credit are incomplete and out of order

I just watched Gremlins 2: The New Batch and the WGA locked writing credits aren't as shown onscreen and are also out of order. The "written by" credit occurs during the opening credits and the "based on characters created by" is actually the last credit in the ending credits. The should be:

Charles S. Haas                    (written by) (as Charlies Haas)                        1,1,1

Chris Columbus                   (based on characters created by)                   2,1,1
