Xshell 5 cann't list sessions with 'list' command [1]

the 'help' command show as follows,
---------------
list: Lists information of all available sessions.
'ls' and 'dir' do the same.
---------------
but when running any of 'ls', 'dir' and 'list', the output always is local file and directory lists, not the session lists.

how do i list all my sessions?

Program Ver. : Xshell 5

We understand that the ls and list commands can be confusing to use with our current settings. Our team is working on improving this. Thank you for your patience.
