If what you are saying is correct, then I doubt there is a bug. Many machines only read DIP status upon startup and changing DIP status and not restarting/rebooting the machine will result in some/all changes not taking effect.

It is always safest to make desired DIP changes and then hit F3 although I would suggest SHIFT+F3 to hard reset the machine akin to fully powering off/on quickly. Doing it any other way is not guaranteed and will only work if the program is made to check DIP changes on the fly, which it appears these game do not.
