Drawing Rules in AECOsim

I am using the update 1 version of AECOsim 08.11.09.376 and been finding some strange behaviour when trying to edit the Architectural Rules.

I go to the Architectural tab on the Building View settings and see the list of Rules available if I select one and go 'Edit Rule' the second dialog opens but is empty !!!! (See Below)

 

I can go to other projects and it is populated ?? If I try to ADD a new rule it will allow me to create it and it will appear on the right dialog window but then will not allow me to 'Add' it to the list on the left.

Has anyone seen this or have any idea what is causing it ??

 

Thanks & Regards
