history() and history_range() return NA values but raw JSON does not

I'm using rwunderground 0.1.6, R 3.4.2 on Windows 7. This code:

h1 <- history(set_location(PWS_id = "INEWSOUT879"), date = 20170103, use_metric = TRUE)

returns a data frame where the values for viz and for all variables after the pressure column are NA.

However, the raw JSON for the same request:

http://api.wunderground.com/api/261d580a0cf44286/history_20170103/q/pws:INEWSOUT879.json

returns values for these variables. For example, the last observation for precipm is 4.3.

I see the same issue using history_range(), but not using history_daily().
