Duration Not Working

Hi, I’ve tried everything, but I can’t get the duration to show up. I am using Libsyn & Blubrry. Tried switching to Podlove to use the shortcode, but it didn’t play nice with WP Engine. (or WP 3.9.1, I updated this afternoon and am not sure which was the problem)

Here is the URL I am working on: https://triberocket.com/podcast-2/

And here is the element code.

`<tr>
<td>%DATE%</td>
<td>
%TITLE%</td>
<td>%POST_META|duration%</td>
</tr>

Love the plugin. Just need a little help with this.

Thanks!
