Upon importing my files I have been adding Keywords as I have been in the past. They show up in the Keyword window but when I press enter they disappear and do not appear to be registering in the various categories. Is this a known problem or is there something I am missing? Windows !0 Lightroom CC 2015
try restarting Lightroom and/or restarting your computer
Thanks I should have thought of rebooting, and it worked. I had tried restarting Lightroom, but of course when all else fails, reboot.
