allOf incorrectly uses discriminate type

[er1c]

    yield:
      type: object
      properties:
        product:
          type: string
      required:
        - product
    YieldWithWeight:
      allOf:
        - $ref: '#/components/schemas/yield'
        - type: object
          properties:
            weight:
              type: integer
              description: |
                Weight amount
          required:
            - weight

Produces:

package org.myapi
sealed trait `yield` {
  val product: String
}
object `yield` {
  implicit val customConfig: io.circe.generic.extras.Configuration = io.circe.generic.extras.Configuration.default.withDefaults.withDiscriminator("type")
  case class YieldWithWeight (
    weight: Int, product: String
  ) extends `yield`
}

I would expect to be able and create both a yield("foo") and a YieldWithWeight(10, "foo") since both are valid objects. Need to think through how this code should actually be generated though (forgive the yield) was working on fixing the reserved words escaping.
