Featured Images showing on posts

I have theme-options/layout-options set to (show full content - no feature image), but the site origin post carousel will not work without the featured images it seems (for which I am using a 350x500 medium thumbnail size showing 2 at a time). See here...under Upcoming events: https://tangledgardenherbs.ca/tangledgardenherbs.ca/ (test site) When featured images are added to a post the images show up on the post (front end), (which I don't want) and are distorted in size to a full default size which I don't know how to set differently (see. https://tangledgardenherbs.ca/tangledgardenherbs.ca/home/blog-updates/) If I have the setting for layout as (show full content - no feature image) why are they showing up on the posts. Is there a way to hide them from posts and pages, and have the images within the post content show up instead. I have set the Single Page/Post Image Layout to full or disabled, but neither makes a difference. On the blog page - https://tangledgardenherbs.ca/tangledgardenherbs.ca/home/blog-updates/ 'The day with roses' post has the featured image removed so is showing properly, but then it is not showing up in the slider here: https://tangledgardenherbs.ca/tangledgardenherbs.ca/ (test site)
