At this time, we have an open bug report on the issue you reported regarding categories not displaying in chronological order. We will continue to track the bug, but at this time it is uncertain when it will be resolved.
Thankfully, your content will continue to display within your channel, albeit out of order. If you were to convert your feed to the JSON feed format, then you could configure a "playlist" within your feed. Essentially, a playlist acts as any other category in your channel, but it allows the publisher to control the order that the content appears in. This is one potential solution for you to fix the display of your category.
If you do not convert to JSON, then I suggest that you check-in with us again early next quarter to see if there have been updates on this ticket.
yes the bug is in the json feeds as well... I even went as far as to order my json files in the episode order and they appear in a different "random" order everytime I upload an updated json file. It's amazing how this "bug" is ok in a public channel, but a shitty graphic file is not, I guess there's more to, make it look good over "make it work" modern philosophy I keep seeing everywhere..
