Can't extends multiple interfaces

[okenoruk]

Hello! I encountered a problem when generating diagram.

Example content-object.model.ts:

export interface ContentObject extends PageOption, BaseContentModel {
  id: number;
  type: string;
  name: string;
  label: string;
}

When I produce the UML file, there should have be two extend arrows (Pageoption and Basecontentmodel) but it only had one to PageOption interface.

Results in

ContentObject ⇒ PageOption
