Selecting a certain spelling/pronunciation for Japanese words

Hello every one, I’ve imported a lesson from Netflix and Lingq uses for many Kanji the wrong spelling/pronuciation e.g. 内 is spelled うち while it should be ない in this context. I figured that I somitemes get the right spelling if I remove(or add) spaces between the Kanji, but is there a way to set the spelling manually?

Some imported lessons will require editing to improve the lesson quality - particularly when the imported source file is a Youtube video with automatically-generated captions.
