Series Ordering

I'm trying to setup a menu item for a Series list. The idea is to display all series on a page. But the ordering isn't working correctly. Would like to have the series with the most recent sermon displayed first. Currently, it's not working that way. I can't figure out what it's doing. I try setting the series list by date and it doesn't even post the latest created series first. No matter if I set it ascending to descending. So, trying to figure out how to do this. Is it possible?

website is www.fellowshipsearcy.org/index.php/resources/teachings

The series are always ordered using the "Ordering" column.
That ordering can be adjusted by moving the series into the desired order in the backend series manager. For that you need to sort the list by the ordering column first and then you can drag and drop the series using the three dots on the left of the entry.

The option "Default ordering" relates to the sermons within a series.

That's the way I have it set now and it still does that. I set the ordering in the backend the way I want it, but it still displays incorrectly.

Then you have manually changed the ordering of the list in frontend. Any user can change it by clicking on the table header (assuming you have the table layout). This selection is stored in the session.
Other than that it always orders the list by the "ordering" column, which can be adjusted the way I described above.

Thanks for the guidance, but it's still acting strange. I've cleared all settings and cookies for the site and I haven't sorted by the table heading.

The attachments contain what it looks like in the backend (table sorted by Ordering: ascending) and the corresponding frontend view.

Any assistance is appreciated.

Thanks!

Can you check the database table #__sermon_series? "#__" will be your Joomla database prefix.
Check the ordering column for those records if they have a value bigger than 0.
