Any could help me, and know what it mean?

I have problem with packet or rather fragments of packet.
for example (screen 2nd) I have recieved 11799 B of 48000.
And debug logs isn't tell me anything or I cant read logs appropriate

is ZZZ value says how many Bytes I have already read?
but it dosnt make sens becasue on 2nd picture I have 0B (0 value)

ZZZ means the data size in you WND. ZZZ = MAX WND( in your config is 44200) - current WND.
