Custom Theme | Total.text | plus amount

We have been using custom theme successfully for quite some time. Recently, it is noted that late fee is not added with ‘Payable after due date’

Following are the extract of codes:

Quote

                <tr>
                <td class="text-right" colspan="{{ table.columns | size | minus:1 }}" style="padding: 0.5px;font-size: 6px {% if total.emphasis == true %} ;font-weight: bold{% endif %}"> Payable After Due Date
                </td>
                {% for total in table.totals %}
                    {% if total.label != 'Total' %}{% continue %}{% endif %}
                    {% assign Monthly_Fine = '200' %}
                    <td class="border-start border-end text-right" style="white-space: nowrap; border-bottom-width: 1px; padding: 0.5px;font-size: 6px {% if total.emphasis == true %}; font-weight: bold{% endif %}">{{ total.text | abs | plus : 200 | number_with_delimiter: delimiter: ',' }}</td>
                {% endfor %}
                </tr>

Un-Quote

We would appreciate prompt assistance to resolve the issue, it might be related to some updates in format or some mistake we might have not considered earlier.
