Two questions about fcitx5-zhuyin

[lunarythia]

1. It seems like fcitx5-zhuyin prefers Hong Kong standard characters (裏、爲) over Taiwanese. In fact, I cannot find the standard Taiwanese characters at all near the top of the list!
2. Inputting ㄋㄚˇㄌㄧˇ and ㄋㄚˋㄌㄧˇ results in 那李 and 哪李. How come there is a dictionary entry for 這裏 but not 那裡 or 哪裡?

I would just use fcitx5-chewing but it does not allow for character selection with the down arrow key (you need to use the number keys to select specific characters which i find annoying and inefficient).
