I have noticed this bug recently, about 1 week ago. So I created 2 components of a menu ---- i.e. Menu Default, Menu Active. Then I combined them as Menu variant and added (on hover) interaction between them.
Then, I duplicated my parent component (Menu default) and renamed the instance into About. When I open my file in prototype mode; when I hover in About (menu) — instead of showing About (active state) my text gets replaced to Menu Active (Its parent variant)
