You may have to just try and get along with your sub for now and explain things to your real manager when he returns so he'll know that the other girl hasn't been trained properly. Or maybe you can talk to the new girl and explain that she isn't being trained right and that she should probably consult with you if she has any questions. Tell her that there's no sense in having to be trained twice for the same job. Tough decisions. I hope that everything works out.
