Overlapping fields can be merged - error with types

[jBosak98]

Hello, I'm trying to validate a query using wundergraph tools. I have a problem with the validation rule FieldSelectionMerging.
I have a very big graphql schema, but in order to show you the example, I will use only a small piece of it:

interface Animal {
  id: ID!
}
interface DetachedHouse {
  id: ID!
}
interface Flat {
  id: ID!
}
type Dog implements Animal {
  id: ID!
  home: DetachedHouse!
}
type Cat implements Animal {
  id: ID!
  home: Flat!
}
type AdoptedLocation implements Flat & DetachedHouse {
  id: ID!
  address: String!
}
type Query {
  animals: [Animal]
}

With this schema, the query I want to run is:

}
query getAnimals{
  animals {
    ... on Dog {
      home {
        ... on AdoptedLocation {
          id
          address
        }
      }
    }
    ... on Cat {
      home {
        ... on AdoptedLocation {
          id
          address
        }
      }
    }
  }
}

The response of the validation with the FieldSelectionMerging rule is error differing types 'DetachedHouse!' and 'Flat!' for objectName 'home'
In fact, the query is an example of mixin/diamond. From my point of view, there should be no errors here.
