Problem with JeeHell A320 FMGS

[Beaufort]

Since a past update JeeHell A320 FMGS uses a special own parking brake and prevents FSX´s own standard parking brake to be applied. Therefore GSX´s actions can neither be initiated nor be stopped. Is there any possibility to separate this from FSX´s parking brake, e.g. by assigning another action, pushbutton or keystroke?
THX for any help!

GSX supports a non-standard parking brake, we used this to support the Aerosoft A320 and we'll use it the upcoming A320 from FS Labs.

However, the feature cannot be added by users, so it's best if you could give me more informations about this product.
