If I understand the relevant code properly, this should happen only when
you try to extend a service type (eg. slim-service-type) with another
service, but you have multiple instances of the given service type, and
so guix system can't disambiguate between the two (it would be better if
you could manually specify that imho, but alas).  Could you post a
snippet of your config, especially the service part?

Best,
