Figmular Plugin Wrong Export

Hi dears! I am a newbie regarding Figma. Allow me to ask some questions: I created a button component (with some variants) and a frame that includes some instances of this component. There is also a hover on this button defined in the prototype section. After the export of my frame (with all instances and component code of the button component), I created a new litlle Angular project with the export code. But after calling localhost:4200 I only can see buttons with width of 0x (but the correct height) and no hovering is visible. Whats wrong here? I am thankful for any help! 🙂
