Futzing with wreck spawns - what did I do wrong?

[CitizenIosef` 7]

So I cracked open the fnc_wrecks.sqf file to see if I could have them generate themed loot. I wanted my players to be able to walk up to a wreck and tell what nationality that wreck belonged to. As the wrecks file supported multiple loot tables, this seemed an ideal place to start.

I started off with this file:

And made edits to the loot tables, which resulted in...

Predictably, wrecks no longer show up at all. I've double and triple checked my classname numbers to loot chance numbers - all are 25 entries. I've checked my syntax, and it looks good... What am I missing here?

Thanks!
