   * - :bdg-warning:`Warning` The selected shorelines layer (``<shorelines layer name>``) has less than 2 fields.
     - QSCAT requires the selected shorelines layer to have the two fields for ``date`` and ``uncertainty`` field.
   * - :bdg-warning:`Warning` The selected shorelines layer (``<shorelines layer name>``) has invalid date inputs: ``<10 or less invalid dates shown>``.
     - QSCAT requires the selected shorelines layer to have valid date inputs in the ``date`` field. The date should be in the format of ``MM/YYYY``, and values of 1-12 for month and 1900-2100 for year.
