The problem is that you copy-pasted the configuration lines without understanding what they mean.
LeatherJacket.swf contains three components: overtop, armwear, and collar.
If we loaded this with a minimal config line, then each component would get assigned to its selector. The main part of the jacket would appear in the Top selector, the armwear (i.e. lower sleeves of the jacket) would go into the Gloves selector, and the jacket's collar would appear in the Collar selector.
This is inconvenient. In order to get the whole jacket to appear, we're forced to perform three sets of clicks.
So, instead, we assign all three parts of the leather jacket to the body selector. Now, we need only choose "Jacket" and click once to make all three parts appear.

The problem is that you applied this same approach to CT-PunkLeatherJacketOvertop.swf. That's a different file. It's a short-sleeve design (hence: it lacks an Armwear component). It also lacks a Collar component -- the upper portion is simply an extension of the top itself
(which means that it won't track the neck movement perfectly, but it has simply been designed with enough slack so that the neck doesn't clip through during gameplay).
When you try to load it with a copy-pasted version of the previous config line, moreClothing gets confused because you're giving it instructions about
"what to do with the sleeves and collar" -- neither of those things actually
exist.
So the solution is to reduce the fancy config line to a simpler one:
