Can’t get the posts to show up correctly

Ok, I’m a complete newbie to making custom WordPress themes, so excuse me. This is probably something very easy to fix.

Anyway, if you take a look at the site here: https://www.chamillionairefans.com/test/

I’m having problems with the posts on the first page. It’s working fine when I just have 1 post. But as soon as I add another post, it messes up the site.

As you can see, there’s 2 posts there. But only one bar with the date and read more link and comments link. And the read more link is linked to the top post, not the post it’s located below.

I would really appreciate if someone could tell me what I’m doing wrong here.

Thank you!
