Separate podcasts intermixing in rss feed.

I will try and explain this clearly, I have had a podcast setup that has been working fine. iTunes connected. no problems

I recently wanted to create a new podcast with a different category, series and speaker. So I created the new items, then uploaded my sermons into the new category/series. Now, those sermons are populating in my other series in RSS and iTunes? I can separate them on the sermonspeaker pages on the site, but they're intermixing in the feeds. I have created a new RSS page for the new podcast series, which works, however these are also populating in the original RSS feed as well.

Additionally, It seems that the sermoncast feed is only populating like 10 or so items. Why is that? I must have something misconfigured or something. I would really like to have 2 separate feeds with different items in each, I can do that correct?

I'm using Joomla 3.5.1 and SS 5.4.5

Thanks for your assistance.

By default, the RSS feed will display sermons from all categories. You can filter it using a menu item or by appending the category id as URL parameter (&catid=123).
The sermon listings also have the link to the corresponding RSS feed in the header of the page.

How many items are shown depends on the "Feed Length" setting in your global Joomla configuration.

Ok, Thanks I think that makes sense, would SEF URLs also be problematic in this case I assume?

SEF URLs should work fine.
