New shows not updating to Library

I scanned for a minute to find if anyone else had posted this question and didn’t see it.
I have a firestick and I have created a library following all the instructions you can find, but my shows will not update with new episodes.
For example, I have added Dr. Phil to my Library to test it. This show airs daily so new episodes should come up in my library or ‘This Weeks TV’ playlist I created.
nothing.
The only episodes that are present are the ones that were available when I first added it to the library. I have ran the ‘Update Library’ and it still does not pull in new episodes. I am not super techy so please give me step by step instructions so I can see where I went wrong.
I am using SALTS as my source
