I've had the chest wound on the Allfather before as well. It's rather annoying. I have not noticed that it inflicts DOUBLE encumberance, however.

There are, however, some encumberance numbers to take into account: The "base" encumberance never changes. For the AF, this number is "2".

The melee encumberance is equal to the base encumberance, plus any afflictions, plus any weather penalties, plus any armor encumberance. If you're inside cold-3, you'll notice that a +2 is added on for "Severe Cold". The Allfather is mounted and does not suffer armor encumberance. A chest wound does not affect the melee encumberance of a 0-encumberance chassis. This encumberance is added on every turn that you attack. Note that Quickness will cause you attack twice, and therefore incur double this encumberance. This is not displayed, however.

If you're seeing an actual +12 enc melee, due to the chest wound, take a screenshot so we can analyze it.

The spellcasting encumberance is equal to the base encumberance, plus TWICE the armor encumberance. Note that this value is nonzero even if you are a 0-encumberance unit. This encumberance is added on every time you cast a spell, in addition to the fatigue imposed by the spell.
