How to modify texts in a variants with the prototype mode ?

Hi there,
 

I try to modify texts in a variant of my « Select » component instance.

I choose the « Open » state in the component properties menu, and when it is open I write « Text » in the first item.

I put back the « Default State », I switch to the prototype mode, and when I click on the component, I see the old text of the master component.

How do I keep editing texts in a select open in an instance component?
