Collections -> Won't Order Channels on Client as Arranged on Server

I made a couple of collections to make it easier for my wife to access the channels she watches and then for me to have the channels I watch. But, regardless of how I set the order on the server, it puts them in mostly correct order with a few at end that are out of order.

Edit: Also, the guide outside of collections (HD/Favorites/etc.) display duplicates of some channels, (the collections correctly hide duplicates).

Are there steps that I might be missing?

What client device?

Firestick 4K...guide is ordered correctly on my phone (iOS).
