All Channels Option in Live TV No Longer Listing Channels In Order

I usually log in to my Xfinity Stream online, and easily find my complete channel listing in channel # order, under All Channels on the Live TV tab. However, tonight I logged in & find my channel listing completely out of order. Seems the channels are grouped in some odd way now, such that I have to scroll & scroll, and randomly find the channels I want.

How do I get my Live TV channels to once again appear in order by channel number? I cannot seem to find a function to restore that view, and not sure how it got this new way just tonight. Any thoughts on this?
