You can disable the fix if you don’t need it. Please see: https://calva.io/output/#repl-process-output-stdout-and-stderr for more on this. The awaitable thing makes for an easier way for you as a user to create commands like Clear REPL output. (Used to need #joyride , now can be solved with the VS Code built-in https://code.visualstudio.com/docs/getstarted/keybindings#_running-multiple-commands only.) See the above thread for more on that.
