On a related note, I found for certain that if you delete all profiles, the Vault Explorer is attempting to access the <<Vanilla>> profile, so it recreates it on purpose.
One 'crazy' solution would be to replace the <<Vanilla>> profile with a copy of the company standard profile in the UserCacheData folder, but then if you need root vanilla back, you would have to get it from disc, or some other cleaver backup means. In addition you would want to do the same to the default mechanical profile, that was all 3 profiles are the same.
So simply put, where does the Vault Explorer store the list of profiles it is trying to use. Allow to Modify that list, and were done here.
