Help with some blocks/coding on my theme.

[candicenowrise]

Hi. Im having an issue. I would like to add a centered text block to add some descriptions for the services im providing below that title BATH & HAIRCUT PACKAGE. I would like to have this descriptive text block where I drawed the red square.

but when I click on add column it only lets me add text column with images 

I tried to do it withing the code with no luck. Maybe im doing it wrong. Here is the code:

{% if section.settings.divider %}<div class="section--divider">{% endif %}

<div class="page-width">
  {% if section.settings.title != blank %}
    <div class="section-header text-{{ section.settings.align_text }}">
      <h2>{{ section.settings.title }}</h2>
    </div>
  {% endif %}

  <div class="grid {% unless section.blocks.size == 5 %}grid--uniform{% endunless %} grid--flush-bottom">
    {%- assign grid_item_width = 'medium-up--one-third' -%}
    {% case section.blocks.size %}
      {% when 1 %}
        {%- assign grid_item_width = 'medium-up--one-half' -%}
      {% when 2 %}
        {%- assign grid_item_width = 'medium-up--one-half' -%}
      {% when 4 %}
        {%- assign grid_item_width = 'medium-up--one-half' -%}
    {% endcase %}
    {% for block in section.blocks %}
      {% if section.blocks.size == 5 and forloop.index < 3 %}
        {%- assign column_width = 'medium-up--one-half' -%}
      {% else %}
        {%- assign column_width = grid_item_width -%}
      {% endif %}
      <div class="grid__item {{ column_width }} text-{{ section.settings.align_text }}" {{ block.shopify_attributes }} data-aos="row-of-3">
        {% if block.settings.enable_image %}
          <div style="{% if section.settings.align_text == 'center' %}margin: 0 auto;{% endif %} max-width: {{ block.settings.image_width }}px;">
            {% if block.settings.button_link != blank %}
              <a href="{{ block.settings.button_link }}">
            {% endif %}
            {% if block.settings.image != blank %}
              <div class="image-wrap text-spacing" style="height: 0; padding-bottom: {{ 100 | divided_by: block.settings.image.aspect_ratio }}%;">
                {%- assign img_url = block.settings.image | img_url: '1x1' | replace: '_1x1.', '_{width}x.' -%}
                <img class="lazyload"
                    data-src="{{ img_url }}"
                    data-widths="[180, 360, 540, 720, 900, 1080]"
                    data-aspectratio="{{ block.settings.image.aspect_ratio }}"
                    data-sizes="auto"
                    alt="{{ block.settings.image.alt }}">
              </div>
            {% else %}
              <div class="image-wrap text-spacing">{{ 'image' | placeholder_svg_tag: 'placeholder-svg' }}</div>
            {% endif %}
            {% if block.settings.button_link != blank %}
              </a>
            {% endif %}
