Wrong mems shown for word 약점

For some reason the word ‘약점’ is showing 6 mems for the word ‘약국’.

I thought that it’s possible that the word 약점 could have the meaning of 약국 (drugstore) because the characters alone could have that meaning (점 can sometimes be related to market stalls). That meaning is in one dictionary, but it’s rather uncommon. Uncommon enough that it has no sample sentences.
Note: this is a platform issue; I’ve seen it on android and on the web. If a mod wants to move it to wherever general/platform wide issues go, please feel free~!

The word is in this course https://www.memrise.com/course/966311/sogang-5b-chapter-4/
