Вкладки React Toolbox дают ошибку при использовании в ThemeProvider

App.jsx - это:

<ThemeProvider theme = {theme}>
  <div>
    <Tabs index = {0}>
      <Tab label='Primary'><small>1Primary content</small></Tab>
      <Tab  label='Secondary'><small>Sec content</small></Tab>
    </Tabs>
    <Input label = "test"/>
  </div>
</ThemeProvider>

Ошибка:

TypeError: Cannot read property 'pointer' of undefined Tabs.render @ line 240 var classNamePointer = (0, _classnames4.default)(theme.pointer, _defineProperty({}, theme.disableAnimation, disableAnimatedBottomBorder));
