  Select the Start of the Block:
  
  Go back to the screen where you are prompted to select a block or range.

  Check Input Fields:
  
  Verify that all mandatory fields related to block selection are filled.
  Sometimes the UI might have separate fields for start and end of the block; both need to be populated.
