My original problem was that many of the words in my wordbank did not have audio.
At the time I had the page display set to 50 per page and near the bottom of the page the words would not have audio. Page to page was different one page the last 8 words had no sound and the next page the last 3 words had no sound.
I reset to 20 words per page and all words now have audio so there is a bug if you set your page view to 50 words per page.
while checking all 293 entries (beginner series only) I found the following 3 words to have vocabulary audio mis-match based on the pinyin. I am not able to tell if there are mistakes with any words based on the hanzi.
是 是 shì to be
热 熱 rè hot
行 行 xíng ok
