Well, in this specific case some rules are applied, since hashcat was instructed to apply all these rules, but they/some didn't change the password candidate because the toggles should take place at positions that are outside the password candidate's password length.
I.e. if you toggle like this:
apply "T9" to "word" than the result is "word"
since there is no position 9(+1, because first position is 0) in "word".
I would say that this is somehow to be expected behaviour since hashcat can't by no means keep track of all current and previous password candidate and filter/unique them, because word lists and number of rules could be huge etc.
So in this case the answer is "don't apply rules that do not change the plains within your word list" and in general the answer (even if not 100% "acceptable" all the time, I guess) "ignore the few duplicates, since if your candidates/rules are good enough there should be very, very neglectable little".
