[confirmed]Meld pairs stay in exile, melded in graveyard

Describe the bug:
When I meld Graf Rats // Chittering Host and Midnight Scavengers // Chittering Host, copies of the Rats and Scavengers stay in exile despite the big ugly Chittering Host on my battlefield. When I Terror the Chittering Host, there's a Chittering Host in my graveyard.

Which card behaved improperly?

Graf Rats: {1}

| Creature - Rat | 2/1 | At the beginning of combat on your turn, if you both own and control Graf Rats and a creature named Midnight Scavengers, exile them, then meld them into Chittering Host.
Midnight Scavengers: {4}

| Creature - Human Rogue | 3/3 | When Midnight Scavengers enters the battlefield, you may return target creature card with converted mana cost 3 or less from your graveyard to your hand.
Chittering Host: - | Creature - Eldrazi Horror | 5/6 | Haste / Menace (This creature can't be blocked except by two or more creatures.) / When Chittering Host enters the battlefield, other creatures you control get +1/+0 and gain menace until end of turn.

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Dev 4721c01.

What exactly should be the correct behavior/interaction?
The two cards should come out of exile when they meld, and the meld card should split back into its parts when it goes into a graveyard.

Are any other cards possibly affected by this bug?
Brisela, Voice of Nightmares and her parts, though I can't check her because she freezes the game.
Hanweir, the Writhing Township and its parts, though I didn't check it because I'm lazy.

Also because I'm lazy, I didn't check its interaction with going to a player's hand (Unsummon), exile (Swords to Plowshares), another zone and back again as part of the same effect (Otherworldly Journey), or the command zone. Short version: it splits whenever it leaves the bf, and if something does something to a card while moving it off the bf, it does it to both parts. Long version: rule 712 (and 909.3a for the command zone, if you needed more proof that whoever writes the comp rules hates programmers).
