Input 'ssue on MAC Terminal

I am trying to use local terminal on RDM but somehow input method is not correct and it acts weird. When i try to delete with backspace it moves forward and doesn't delete. Tried 3 backspace methods on terminal type setting without success. There i another issue as well, when i try to execute commands terminal on RDM says zsh command not found. even on simple commands like "ls" if I enter PATH variable (/usr/sbin) it connects to pwsh. and other commands start working. Removed reinstalled many times and it is driving me nuts.

Any thoughts?

EDIT:

PATH variable: export PATH="/usr/bin:/bin:/usr/sbin:/sbin:$PATH"
and after that I am able to run pwsh command whic runs Powershell so I can connect to Exchange online
