Hi, Burk! I can confirm to you that I'm having the same design on the Stats page.
I have two tabs - All & Responses when I access the notifications tray from any page, EXCEPT for the Stats page.
On the stats page, just like you, I'm getting them all mixed up, in one column.
You are not alone. I see this on both my tablet and my smartphone, in the web browser (I dont' do the mobile app too much) :D
