Field labels displayed as identifier

In some areas in the TYPO3 backend fields created by Content Blocks are displayed with their identifier instead of the localized label. E.g. in the backend user permissions view or the list view / export view. The reason is that you can't define fields centrally in Content Blocks. Multiple Content Blocks can reuse the same field and define alternative labels. If you really need proper labels in these areas, we recommend to use TCA overrides in order to define a default label.

$GLOBALS['TCA']['tt_content']['columns']['my_prefix_my_identifier']['label'] = 'LLL:EXT:my_extension/path/to/locallang.xlf';
