Clarification on 师 meaning I am trying to learn some vocabulary thanks to memrise.com.

In the word list, 师 is mentionned two times, once meaning "teacher"(pinyin: shi1), the second one as an adjective meaning "handsome, smart" (pinyin shuai4).

I can't find the second meaning anywhere else online. Is this an error from the site, or something deprecated or unusual ?
Similar characters:
师 shi1

帅 shuai4

I would imagine someone mixed them up accidentally.
