I see one problem, which is probably not what is bugging you, and perhaps somewhat my fult. The I.D. defines separate pieces for the King to morph in (good), but these are not marked as royal. There should have been a line royal=KJLMO in the description, but it turns out the new PTA is not so finished yet as I thought, and that the text entry for defining royal pieces is still ignored. (That is what you get if you take a long pause in developing something...)
So the I.D. doesn't understand these morphed Kings are royal, and as a consequence also has not passed that info to the GAME code. This could be fixed directly in the GAME code by adding lines in the Pre-Game section
set wroyal (K J L M O);
set broyal (k j l m o);
About the label-image assignment: you should be able to use a custom set that uses exactly the limages that you want for the labels of your choice. Select a Set Group 'Custom', and then a Set 'Completely Custom' in the preset Edit page, and paste the text the PTA suggests for this section. (Oh, problem: the new PTA does not suggest this yet, as it is a feature that was only introduced after I made that. But you can use the old PTA to generate that, and only use the custom-set output from it.)
