Do you have the original grouped .obj file? If so import it into your modeler and check to see if the uv data is intact. Do you have the .cr2 that has the faulty uv data? If so, save it to your figure library. Import the double checked .obj into poser. Enter the set-up room. Load the .cr2 from your library. Exit the set up room. Load your corresponding textures. Is the uv data lost?
