Checkbox doesn't display label

[edoelk]

  <Checkbox
    checked={!hasExpirationDate()}
    onChange={(event) => setHasExpirationDate(!hasExpirationDate()) }
    label={'This label is not displayed!'} />

Any ideas? Thank you.

I usually wrap it in a FormControlLabel, e.g.

<FormControlLabel
      control={
            <Checkbox
                checked={!hasExpirationDate()}
                onChange={(event) => setHasExpirationDate(!hasExpirationDate()) }
            />
      }
      label="This label is displayed" />
