I am trying to reuse a part of my previous project, hence I created snippets for both schematic and pcb layout (see https://www.youtube.com/watch?v=R3HyuQ_N23A)
However, when placing the snippets in a new schematic page, all designators are changed to question mark (like C?) thus unable to sync with the pcb layout. How can I keep the designator when placing them in the schematic. Is this related to copy-paste behavior? Usually when paste a component its designator change to a question mark.
