Midnight Commander Subshell doesn't work

Hello people.

I've just installed the most recent build of LE for RPi4 and installed system-tools addon from official repo to get Midnight Commander but i am a bit confused with few things.

1. There are no prompt within mc.

And standard linux enviroment variables have no effect in mc?

Where may i define cmd prompt format in LibreELEC ?

2. Subshell output is not visible.

I can execute command (like mkdir etc) BUT i cannot see i'ts output after CTRL+O.

E.g. i execute "ps ax", then do CTRL+O and console appears to be empty:

Same in subshell mode. But in subshell mode i cannot even see what i am typing. i can type "mkdir bbb" and directory will be created but no output at all

Can this be fixed ?

br,

Thank you for your reply tokul.

I've tried that before. Disabling subshell with -u really brings described behavior and I can see hash prompt as well as output after CTRL+O

But i get used to do something under CTRL+O with file directory or editor/viewer on background (scripting/sqlite3 browse / etc)

As far as i understand there is no chance for that with LE under RPi4 ?

Got it. Thanks a lot.
