[OKDXA] FT8 Ignorance...

I'm puzzling over what I'm seeing in my WSJT-X windows.
I underrated the two window's function: the left window shows everything
decoded in the receive passband, while the right window shows what's
decoded on my specific rx frequency. The rx frequency must have it's own
(narrow) passband (1 Hz? 0.1 Hz? 0.001 Hz?), but I'll leave that for now.
What puzzles me is how to interpret that the following in my left window:
193245 -14 0.2 1839 ~ FT8WW N2CEP -15
193315 -10 0.2 1839 ~ FT8WW N2CEP -15
193415 -14 0.2 1839 ~ FT8WW N2CEP -15
193445 -16 0.2 1839 ~ FT8WW N2CEP -15
193615 -14 0.2 1839 ~ FT8WW N2CEP -15
194345 -15 -0.0 1891 ~ FT8WW N4FAC +14
194415 -19 -0.0 1892 ~ FT8WW N4FAC +14
194515 -19 -0.0 1892 ~ FT8WW N4FAC +14
I understand the columns (in order) as UTC time SNR (dB),
time-offset-from-expected, frequency (Hz). Now comes my confusion in the
"Message" column: is N2CEP calling FT8WW, or is FT8WW responding to
N2CEP? What's the number (-15)? I never see any of the responses from
any station RR73, etc. In one case (line not shown), the Message
consists of HR5/F2JD <KG4USN> 73. That sort of makes sense, but again,
I've never seeen anything I can put together as an entire QSO anywhere,
ever.
What am I doing wrong?
73,
