Your tab is pointing to your choices sheet as well as your choice component. Your choices should be separate from where you want to write the selected value. What’s happening is you are trying to set your selected choice (female) back to the same column where you store the choices, so it’s overwriting the value of the first row you are editing (male) in your first column with your selected choice (female).
All sheet need to have headers in the first row, which glide will then recognize as the column name. Any rows after that are your data rows.
I like to have a separate sheet that holds all of my choice values.
