likely because it is filler. The only reason why the amagai arc got a promo was due to new Bleach episodes being on hiatus for almost 9 months, so they did it to "promote" interest back in Bleach. Adult Swim only advertises excessively to shows that make them more money directly or to spark interests in new shows. Bleach is popular enough (and has been on the air for over five years now) and pretty much promotes itself. Fans know when it is on, so there really isn't any need to promote it.
