Selecting an Enum in a column deletes another column Enum entry

[Appdev1]

Hi everyone,

using Appsheet to develop an app.
I am struggling with a problem. I have two columns, let’s call them A and B.
Within each column I have set enum (buttons):

Yes
No

When I select “Yes” in column A, it’s all fine. Then, when I select “Yes” in column B, the previously select “Yes” in column A disappears and I see appearing the “Yes” in column B.
Tried many things, but I can’t solve this.

Could you help me?

Thank you.
