Well, the JavaScript in the wizard page that flushes the GAME code uses this line for generating the promotion array:

        if(choice[i] != 3) psupply += ' ' + ids[i] + ' ' + ids[i].toLowerCase();

The array ids[] contains the piece IDs. It does not take them directly from the promotion string you typed; this just determines the content of the array choice, encoding what type of promotion this is (e.g. to captured pieces only). Only the second occurrence is forced to lower case, and if the IDs already where lower case, the first one stays that. Normally the Diagram takes the IDs as first letter of the name (when not explicitly given in the piece definition), capitalizing it. But in the Play-Test Applet you then in general change the name and the ID (and move). So the likely explanation is that you typed a lower case ID when altering ID / name and move for Wolf and Eagle.

I suppose I should just write ids[i].toUpperCase() for the first occurrence, to exclude this. Or perhaps already convert the ID to upper case in ids[] when you alter it.

I looked at the code in the preset, and I still see one issue: the castling partners do not seem to be defined correctly (e1 e1 e12 e12) instead of (a1 l1 a12 l12). I don't know how that could have happened. This game has castling, does it not? The Interactive Diagram made by Aurelian defines the King move as KisO3.
