I know exactly how to solve this problem as I had it as well. Open Mod Organizer and move over to the Archives tab, scroll down until you find Spice of Life's .bsa and extract it into Spice of lifes mod folder. After this double click on Spice of Life on the left hand pane and go to the filetree tab. After that right click on 1nivVSLArmors.bsa and set to hidden. This should solve it as it did for me but i've yet to test if the mod itself continues to work in game.
