I apologize. It is kind of hard to explain. Say you want to install a mod with different options for textures. Usually when you select the different textures it shows you an image of what you are selecting, so you can decide which you prefer. When I select any of the options the image does not change from what the default option will show you. An example mod being maybe Amidian armor, or Smim. I can select options but I get no preview of what I am selecting. I am using MO 1.3.11. This feature works fine for me in MO2.
