"Body Parts" Survival Guide errors

The phrase 头痛 is shown in Pinyin to be Tóu téng. I found out doing the W2 test that the proper Pinyin for 痛 is Tòng. If I try to enter téng, it will not display 痛 as an option but show 疼 (téng) as one of the options. It also gives yǎnméi (眉毛) as the Pinyin for eyebrows. The proper Pinyin is méimáo. The word 脚踝 is shown in Pinyin to be Jiǎowàn. The Medical Chinese Survival Guide gives the correct Pinyin Jiǎohuái. I try to record these discrepancies by adding the Hanzi to MyVocab but when I enter Pinyin like Jiǎohuái into the meaning, it eventually gets mangled to look like Jiǎohuái instead.

你好Robert C7, I have had a look through this lesson, picked out the mistakes and sent them on through to our technical team for correction. Thanks for pointing some of these out to us and hopefully we can get these fixed up asap. Keep up the good work! - Lin Ping

It looks like this has been cleaned up. Thank you for fixing it.
