Either I'm dumb or there is someting wrong

I’m doing JavaScript Algorithms and Data Structures Projects: Cash Register. And its 5th test seems to be wrong to me. The cash is 20, price is 19.5. So, the change due is 0.5 dollars. And I DO SEE a 1 (1 dollar) after “ONE” . Isn’t 1 greater that 0.5? shouldn’t it return “OPEN” ?
