First and foremost - referring VVD and preparing a design guide is the right approach. That being said, design document should not be a Copy/Paste of VVD , logical/conceptual/physical/functional/non-functional etc etc. points/figures will always be unique to the design and if we don't see that in the document ,it defeats the purpose of design document. Probably if you can have a quick discussion with the team on the document expectation and specifically - points to be covered and the right format, it would be a matter of 1-2 days for a good architect to update those requirements and align with your business needs. So please don't consider this as a showstopper for the project, set the expectation ,get the changes done and move on . Good luck for a successful project completion.
