ssh get sucked after remotely logging to a Ubuntu

I simply launched a windows 10 cmd line.

C:\Users\vanil>ssh

usage: ssh [-46AaCfGgKkMNnqsTtVvXxYy] [-B bind_interface]
[-b bind_address] [-c cipher_spec] [-D [bind_address:]port]
[-E log_file] [-e escape_char] [-F configfile] [-I pkcs11]
[-i identity_file] [-J [user@]host[:port]] [-L address]
[-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port]
[-Q query_option] [-R address] [-S ctl_path] [-W host:port]
[-w local_tun[:remote_tun]] destination [command]

Logged into a Ubuntu workstation remotely from that terminal. The directory of the cmd line is totally messed up:

Last login: Thu Jun 20 18:22:03 2019 from 24.5.30.160

ls
-bash: cd: pls: No such file or directory
ls

cd pytorch

cd pytorch
];alla_att@tesla: /pytorchvanilla_att@tesla:/pytorch$ Connection to 35.227.134.181 closed by remote host.
Connection to 35.227.134.181 closed.

Can anybody please point to a reason and treatment of it? Thanks.

Actual output

Start with the linked Troubleshooting Steps and TTY/PTY support wiki pages, then reproduce the session from Windows 10 cmd to Ubuntu 18.04.1 using the reported ssh command. Compare the expected prompt and directory with the corrupted input and connection output; done means identifying a reproducible cause and documenting or fixing the terminal behavior.
