Custom SubtypeId fields not parsing {labels}

[thenuggster]

Here's just a simple little test: I imagined that entering "${BlockPairName}_${CubeSize}" into the Large and Small custom SubtypeId fields should result in the same output as not having "use custom SubtypeIds" selected at all. But instead, the {label} fields are not parsed into their corresponding identifiers and instead remain as the strings "${BlockPairName}" which causes further problems down the line.
