How can I effectively move H tags on the dawn theme?

[SpiritualHaven]

Trying to move my H tags around but having issues. h1 tag was originally on the logo however I'd like to change it to a rich text snippet. Managed to removed the h1 tag from the logo but struggling to add the h1 and h2 tags to the rich text section. This is my site https://spiritualuk.com/ ideallly changing the h1 tag to spiritual haven then the h2 tag to the description underneath. I've had a look in the rich text.liquid and changed the code but hasn't seemed to of worked have I made a mistake? 

<h1 class="rich-text__heading rte {{ block.settings.heading_size }}" {{ block.shopify_attributes }}>
{{ block.settings.heading | replace: 'p>', 'span>' }}
</h1>
{%- when 'caption' -%}
<p class="rich-text__caption {{ block.settings.text_style }} {{ block.settings.text_style }}--{{ block.settings.text_size }}" {{ block.shopify_attributes }}>
{{ block.settings.caption | escape }}
</p>
{%- when 'text' -%}
<h2 class="rich-text__text rte" {{ block.shopify_attributes }}>
{{ block.settings.text }}
</h2>
