There are a couple of simple typos on the 薄 kanji’s meaning page. There are no spaces between the names of the drop and specialty radical. This is still readable on the item page (because of the blue boxes drawn around the words), but when actually looking at the item in a lesson, the words are written as “dropspecialty”.
Secondly, the second sentence reads “That its specialty.” instead of “That’s its specialty.”
Hope this helps
