Linked Inbox Tile Keeps Showing Up on Start

[evillama]

Lumia 928, Win 8.1 DP - I primarily use Hotmail on my phone, but I do have my Gmail and Yahoo addresses separately linked (not viewable in my main inbox). I rarely check these addresses so I don't keep the Linked Inboxes on my Start screen. Just this last week though I'm noticing that the tile keeps showing up by itself and I have to keep removing it. Used to be it would only reappear after a soft reset, but now it just does it on its own. Any idea what change could've caused this? Last resort will be to just keep it as a tiny unused tile, but that would be a waste of space.
