How can I report wrong things with the kanji for Japanese typing suggestions in OSX?

When typing you get pop ups for the kanji for certain words.

Typing TENKATOU てんかとう yields this abomination 転化等. Googling on it yields no result. It should be 転化糖

It is extremely irritating and counter-educative to have such things pops up. If the users more easily could report such problems things could be much easier, no?

How and where can I contact the makers of this dictionary?
