Native Template Blog Excerpts Not Displaying Correctly

I am having trouble making my blog posts consistently appearing on the Native template. My first 2 blog posts appear in full on the blog landing page, while the third one appears with the preview circle image and the excerpt. I prefer the latter, but I can't remember how I changed the first 2 to not display the excerpts on the landing page. Does anyone know the answer to this? 

Native blog pages display as a list of vertically-stacked posts.

On the landing page:

• Adding a border to the header also adds lines between blog posts.
• The text from the Business name field of the Location tab displays as a location tag.
• Post featured images display as circles above titles for posts with excerpts. Focal points don't apply to these featured images, and they don't appear on mobile.
• Promoted image, gallery, and video blocks display above titles for posts without excerpts.

On individual posts:

• Promoted image, gallery, and video blocks display above titles at the width of the site.
• Navigation for previous and next posts appears above the comments.

Style blog pages and individual posts with these Blog tweaks:

• Choose if dates and categories display above or below the post with Blog meta data. All other metadata always displays below the post.
• Hide or display author names, tags, and categories with Hide author and Hide tags categories.
• Hide or display metadata icons with Hide icons.
• Set the post width with Blog content width.
