It did that for me too. I found out afterwards that plus codes have two forms, a short and long. If you enter just the short form, it won't be accurate without the ", city" part (e.g. 2A6A+1Q is short form, must be entered like "2A6A+1Q, Beijing", long form of that would have another 4-5 letters in front e.g. 7XQW2A6A+1Q)
