Blog Post not reading Markdown?

Hey together,

i got the Skeleton from the Striped Theme. I already got some language changes to the template to got it german. Everything seems working fine.

Now i deleted all the example blog posts and changed from one of the the folder name and the whole to create my first blog post.

After i finished it, i synced it via git and got it online, but their isnt showing Markdown from the frontsite. If i go into the Admin Panel and looking the text everything is working. Anybody know why its isnt rendering the markdown?

here are the blog post:

Best regards
