I'm no help but...
I've personally given up trying to figure this out at there's been too much inconsistency with my live tiles. Sometimes they work, sometimes they don't, or when I have a live tile disabled like with Microsoft Store it'll re-enable itself even though it's off.
Can wait for the next update in hopes it'll help. Next week should be patch Tuesday so you can see it that has a bearing on your problem, I'm betting it won't though.
