Wrong podcast feed when using shortcode

Hello I have found a bug with SSP Plugin.
I have prepared a new fresh wordpress site to summerize. I have two types of posts : – Regular one without podcast
– Posts with podcasts.
I want to use shortcode to show a player in the middle of the post. If I don’t use shortcode podcast feed is ok.

I have create 6 posts :
1. Explanation of my wordpress => Podcast feed is empty => this is normal
2. Post with a podcast without shortcode => Podcast feed with 1 item, the podcast from post #2=> this is normal
3. Regular post without podcast and with podcast feed screenshot => Podcast feed with 1 item, the podcast post #2 => this is normal
4. Post with a podcast without shortcode => Podcast feed has 2 items, podcast from post #2 and not podcast #4 but regular post #3 => This is NOT attended
5. Regular post without podcast and with podcast feed screenshot => Podcast feed has 2 items, podcast from post #2 and not podcast #4 but regular post #5 => This is NOT attended
6. Regular post without podcast and with podcast feed screenshot => Podcast feed has 2 items, podcast from post #2 and not podcast #4 but regular post #6 => This is NOT attended

How do I understand ? I think something is missmatch when using shortcode. Here it is the shortcode I use. Is it correct ?
[podcast_episode episode=”13″ content=”player,details”]

To workaround I’m not using shortcode and I’m checking after each plugin update if podcast feed become as expected.
Can you please help me to solve this issue ?
