Same here, been meaning to ask about zero results with human filter. Last week I would see humans with human filter. This week installed Falcon. Don't know if that is the cause or not but I no longer see any results whatsoever with human filter, totally blank. As a test, I tued Falcon off, tued on Live Traffic, still no results in human filter, so maybe not related to Falcon after all. I know from Google Analytics and Host stats that there are human visitors. Troublesome that WF is not seeing them. Today cleared data with the WF Assistant plugin. If that restores human view I'll add another reply.
