custom logging field %<csssc> does not look right

when I use custom logging field %<csssc>，I found that does not look right：
1. TCP_MISS： return 200
2.TCP_HIT： return 000
like
%<csssc> %<crc> %<csshv> %<pssc>
000 TCP_MISS HTTP/0.0 200
000 TCP_MISS HTTP/0.0 200
000 TCP_REFRESH_MISS HTTP/0.0 200
200 TCP_HIT HTTP/1.1 200
200 TCP_MEM_HIT GET HTTP/1.1 200
my environment is chrome，everytime use ctrl+f5 to refresh
