re. your question, answer is no, you're not doing anything wrong. all controllers types are usually listed (CC#0..127) where the undefined or unnamed ones are, you guessed right, blank.
however, note that only the named/defined RPN/NRPNs are listed on is own listings, because if it were to be exhaustively listed would be just overkill (RPN/NRPN#0..16383, ie. 16K items, mostly of them blank) :)
thanks for all
