Lightroom B&W Presets Mixed with Color Presets

Hello,

I'm running current LR (2015.9). On three machines that I use, a recent update appears to have mixed the standard B&W Filter presets (Yellow, Orange, Red, etc.) with several Color effects filters, such as Aged Photo, Bleach Bypass, etc. They all appear together under the B&W Filter presets and I cannot move the color ones out. I was able to solve this one one machine (running OS X Sierra) by uninstalling and installing LR. Two attempts on the other machines (running OS X Yosemite) left them exactly as they are, even after resetting the preferences. This is very annoying. Does anyone have any suggestions? Thanks!
