Well, screenshot is not required at all when things are clear. Secondly, the audio you are playing is from an embedded buzzsprout podcast and so it will play in buzzsprout player. In short, buzzsprout player is being displayed in your case.
Kindly try to use audio file and then check style will be same like you see in ours. The difference is for the player type. For a normal audio file hosted on the same server that is the style but if an audio file is embedded from a specific player it has style accordingly.
Kindly note as I said earlier you can move to enter your content now. As you have fewer number of posts and we imported that page later than earlier content is either removed by you or changed so it can’t show those things. The thing is once you add more posts and staff members those will show up.
For the slider you can import slider as well.
Dummy/demo pages means to give you layout page and if content is missing in the website you have to add that.
