Question about Devolo Magic 2 WiFi 6 Starter Kit

The Devolo Magic 2 WiFi 6 Multiroom Kit basically consists of the Starter Kit, supplemented with a Magic 2 WiFi 6 extension. Digitec also replaced the extension with another model in my case. It is difficult to judge whether this causes problems or not. In any case, Digitec should not deliver goods that do not correspond to the order without asking.
