Post page not showing full post

Hi,
I wrote a post last night and noticed that the post preview was not showing the full post as I had written it, but rather just the title (in all lower case) and one photo (not a photo I used in the post I had written)

I could not figure out why this was happening but published anyway. The full post as written showed up on my front page feed, but when the link is clicked to go to the separate page for this post, it shows the same thing as the preview, i.e. – just the title and one photo.

My site: https://www.whattodowithlemons.com
The post in question is from 9/15, titled “DIY Wool Felt Laptop Sleeve”

I have tried changing my settings from full text to summary, but this did nothing. Please help!
