Two read more links, one doesn’t work

Hi, thanks for the great support on this plugin. I recently switched to a custom template, and have an issue – I’m using this as my template:

<!-- wp:html -->
<style> .stc-notify-hr { width:100%;} .stc-read-more-a { color: #0170B9} .stc-post-title-a { color: #0170B9;} .stc-unsubscribe-a { color: #0170B9;} .stc-blog-title-a { color: #0170B9;}</style>
<!-- stc: Mandatory command marks start of content -->{{start_content}}
<h3>{{post_title_with_perma_link}}</h3>
<p>{{post_excerpt_with_read_more_link}}</p>
<!-- stc: Mandatory command marks end of content -->{{end_content}}
<!-- stc: Command to draw a line separator -->{{draw_line}}
<p>You are receiving this email because you are subscribed to the <a class="stc-blog-title-a" href="www.myblogurl.com">{{blog_title}}</a> and {{search_reason}}. {{unsubscribe}}</p>
<!-- /wp:html -->

After the post excerpt I’m getting two links like this:
Read More » Click here to read more

The first link (Read More ») doesn’t work – it results in a 404.
The second link (Click here to read more) works.

I only want one link. What am I doing wrong? Thanks!
