Whenever I change a designator in the schematics, the old designator will be placed in grey between parenthesis behind the new one. For some sort of reason Altium decided to give errors on the old designators in combination with the new ones. See pictures below for clarity:
I've tried resetting all designators and annotating them again. Closing the application. Thus far only replacing the part with a new one seems to work. But that isn't doable for a full project.
Has anyone had this problem before or does anyone know what might cause (and solve) this problem?
