Default subcommand: help on error displays repeated main command

[xmedeko]

I have a command with subcommands and one of them is default, see

const options = yargs
  .command(['export'], 'Do export', yargs =>
    yargs
      .command(['csv', '*'], 'Export to CSV',
        {
          'value': { demandOption: true }
        })
      .command('html', 'Export to HTML', { 'value': { demandOption: true } })
      .demandCommand(1)
  )
  .command(['import'], 'Do import', { 'value': { demandOption: true } })
  .help().strict(true).demandCommand(1)
  .parse();

Actual

When a user types wrong subcommand, then the help is wrong:

$ node index.js export foo

Export to CSV                                                                     
                                                         
Commands:                                                                         
  index.js export export  Do export
  index.js export import  Do import
...

Expected

When I remove '*', i.e. the default command flag, from the csv command, then the help is OK:

$ node index.js export foo

Do export                                                                       

Commands:
  index.js export csv   Export to CSV
  index.js export html  Export to HTML
...

@xmedeko a fix for this should now be available in yargs@ 17.7.1.
