Chinese pronunciation does not match the pinyin given.
There are many pronunciations that are not matching the pinyin given by Duo. For example: Duo pronounces 跑 as páo for another Chinese character 刨 but pinyin given is pǎo which is the right pronunciation for the character. I did not write down all of them I found before. But I will post them if I find them again one by one. Chinese is my native language. Hope they know this issue and correct them.
