package bar {
  import foo.Foo
  object Bar {
    Foo.foo(Buz.b) // <-- Quick Fix import on `Buz` won't work
  }
}

package foo {
  object Foo {
    def foo(any: String, theIssueIsThisDefaultArgument: Any = "") {}
  }
}

package buz {
  object Buz {
    val b = ""
  }
}

Given the above code, Quick Fix import on `Buz` won't work. The likely reason seem to be the default argument in Foo.foo. Indeed, if you remove the default argument, then quick fix on `Buz` works as expected!
