External DMD (dll) displays incorrectly on some Gottliebs

[Kraken74]

Some Gottlieb tables are displaying the External DMDs incorrectly. It looks like once a LCD segment has been lit during gameplay, it remains lit, eventually ending up with all segments lit as your score increases. Tested with 998 and 1108. These are used to trigger colorizations.

Some samples:

Gottlieb System 1

Asteroid Annie

Incredible Hulk

Gottlieb System 80

Black Hole

Haunted House

Thanks!
