Intersected (?) layout tabs names

[ValerianMemsk]

Tried to use "nested" grouping like that:

Layout::accordion([
        __('some_key') => Layout::tabs([
          __('main1') => Layout::rows([
            Switcher::make('...')
              ->title(__('admin.enabled'))
              ->help(__('...'))
              ->sendTrueOrFalse()
          ]),
          __('title1') => Layout::periodConfig('...')
        ]),

        __('some_other_key') => Layout::tabs([
          __('main2') => Layout::rows([
            Switcher::make('...')
              ->title(__('admin.enabled'))
              ->help(__('...'))
              ->sendTrueOrFalse(),

            Input::make('...')
              ->title(__('...'))
              ->help(__('...')),
          ]),
          __('title2') => Layout::periodConfig('...')
        ]),
        ...
])        

and found wierd problem. Tabs are in separeted alements of array, but somehow i cannot use same names for them (without nubers) or they symply does not appear. After page is loaded the first "block" works fine, but latter does not work at all. "Active" tabs are shown, but when i clic on second tab ( named 'title' without number, in second block) nothing happening.

I can undersatnd "same name" problems, but not in this case. Tabs blocks are separeted, how could they affect each other and how can i fix it, apart from changing names (names should stay the same cuz its like same functionality for different purpose)?
