Sell chest purchase/placement messages - could be formatted more professionally

I'm not sure if these are easy/practical to fix or not (I'm aware the sell chest plugin isn't custom to OGN) First, "a(n) Tier 1 Sell Chest" should be "a Tier 1 Sell Chest" (all of the sell chests begin with "Tier") Second, "tier-1-sell-chest" doesn't look very professional. Ideally it would say something like "Tier 1 Sell Chest" (I assume it's the internal item name, not sure if easily fixable, but would be nice) See screenshot. First message is on purchase, second is on placement
