Trouble posting podcasts with Blubrry PowerPress

https://www.mischkeroadshow.com/shows

We currently have a Libsyn player for podcasts, but want to switch over to a player from Blubrry PowerPress.

I’d hoped it would be as simple as making a new post each time a new episode of the podcast came out, but new posts go to the blog on the Writing page of the website. The one episode I have been able to post shows up in duplicate (one above, and another below a white line near the website’s credits).

We want the ability to have the podcasts, but also an area where we can put icons for iTunes and an RSS feed.

How do I make sure new posts only go on a certain page of the site? Do I need to change the theme? Or something in settings?

Can anyone help me?

I’m new to WordPress, but I get the feeling this is something simple. At least I hope so.

Thanks in advance!
