Multiple Loops Not Displaying Properly

Hey everybody,

I need to set up the main index on a site to display 3 loops at once, and have each loop display different categories. Only it’s not working properly. Here’s what I want to happen (quotes around the category slugs):

Loop 1: Displays latest post from the “episodes” category.
Loop 2: Displays 2 second-latest posts from “episodes” category.
Loop 3: Displays 5 most recent posts from “blog” and “sitenews” categories.

Instead here’s what’s happening:

Loop 1: Displays latest post from “sitenews” category.
Loop 2: Displays 2 copies of latest post from “sitenews” category.
Loop 3: Displays 5 most recent posts from “blog” and “sitenews” categories.

For whatever reason the “episodes” category is being totally ignored. Here’s the test page: https://chromadile.com/mentalpod/ – And here’s a pastebin of my current main index file: https://pastebin.com/184RWrtZ

Anybody have any ideas?
