tshark protocol statistic differs from wireshark

I tried to get protocol statistic using wireshark with "Statistics -> Protocol Hierarchy" and using tshark with "-r test.pcap -qz io,phs > stat.txt" from pcap file. And for a number of pcap files i got different results (slightly). What does it mean? May be i do somewhat wrong? I like what produce wireshark, but i need to use tshark and tshark's results grieves me.

Below i upload two examples as wireshark and tshark protocol hierarchy results.

At least here we see the difference in BitTorrent section. (Right click -> View Image, for zoom)

Second example. Two protocol trees instead of one.

I can if need upload other examples of various results, which another nature.

Tshark protocol hierarchy results in txt format needs me to parse and represents their in another view.

I use latest version of wireshark and tshark, 2.0.4, and i tried to use last stable version 1.12.12, same results.

Thanks in advance.
