The community member is experiencing an issue with the Google Sheet Typebot block not populating all the worksheets (tabs) from their Google Sheets workbook. They have a workbook with 4 worksheets, but the Typebot block is only showing 3. Another community member suggests that the issue may be due to the spreadsheet not having a unique header row, and provides a link to the relevant documentation. The original poster confirms that the problem was caused by a duplicate header column name.
