One of the parts in question:

The part in question is clearly named wrong. Per the spec, sticker shortcuts are suffixed with dXX. The codes for patterns don't really apply to sticker shortcuts so XX should really just be the next number in sequence that isn't in use. That said, we have one official file in the 4515dXX family that uses "x" so we could go with dsX. I'd prefer the former but can live with the latter.
