I have signed and downloaded the app to give it a look. Those text files (under Profiles sub-folder) are internal parametrization files.
Aircraft profiles/datarefs/custom commands mappings are not open for users to modify. They are hardcoded/compiled on the 'VAInterface.exe' binary (you can open this file via text editor, search for IXEG and you will see there).
I can also confirm VA is using the incorrect datarefs for VS mapping thus the problem you see on the display. I put the correct dataref VA must use for VS display a few posts back on this thread. Correct datarefs & custom commands to use are documented on the aircraft included PDFs (under documentation folder, 2-xxx.pdf)
I am sorry to say you are stuck to VA fixing the profiles and adding new profiles whenever you want to fly another bird
Hope they have plans for releasing an SDK for third party people to develop on top of their hardware without requiring their VA interface and/or they redesign their VA interface for allowing users to create/modify custom profiles by themselves.
