How to mark multiple correct answers in excel

OS** (e.g. Win10): Win11
PsychoPy version** (e.g. 1.84.x): v2021.2.3

I have set a “1-7” scale for a question. And I hope to mark four correct answers in the excel. I have tried some types of marking shown in the following picture. However, none of them works. The feedback always show as “wrong answer”. What should I do to solve this problem in order to make the feedback of this question work?
