Why do I see nvidia-185-modaliases and nvidia-195-modaliases in Ubuntu software updates?

For some reason I see both the Ubuntu 185 and 195 drivers in the Ubuntu Update Manager. In the NVidia X server settings I see the driver as version 185.18.36. I think I managed to install two versions of the NVidia drivers at the same time.
