All selected values must be present in the choiceValues array

Hi. I have a dropdown list. It fails when I select one of the values. Here is the code:

a!localVariables(
  local!formAnswer: {
    function: "",
    subFunction: ""
  },
  local!dynameiceValue: {
    functionList: rule!JRA_QRY_getBusinessOwnerFunctionList_AbbVie(),
    subFunction: rule!JRA_QRY_getbusinessOwnerSubFunctionList_AbbVie(
        businessOwnerFunction: local!formAnswer["function"]
    ),
  },
  {
    a!dropdownField(
      label: "function",
      value:  local!formAnswer["function"],
      placeholder: "select",
      choiceLabels: local!dynameiceValue["functionList"],
      choiceValues: local!dynameiceValue["functionList"],
      saveInto: a!save(local!formAnswer["function"], tostring(save!value))
    )
  }
)

I get the options by query rule and put it into a variable. It looks like good. But it will throw the error when I select the value.

This is the error message:

Interface Definition: Expression evaluation error at function a!dropdownField [line 23]: A dropdown component [label="function"] has an invalid value for "value". All selected values must be present in the choiceValues array, but value was Affiliate and choiceValues was Affiliate; Allergan Aesthetics (AA) Commercial; Commercial; Corporate; Research & Development.

The value "Affiliate" is in the choiceValues. So I do not understand why it fails
