why is SDK Validator saying AudioTypeControl must be an associative array?

I'm attempting to submit a job to MediaConvert, but the validator seems to think both AudioTypeControl and LanguageCodeControl for the outputs needs to be an associative array

Here's the specific error

Found 4 errors while validating the input provided for the CreateJob operation:
\[Settings]\[OutputGroups]\[0]\[Outputs]\[0]\[AudioDescriptions]\[AudioTypeControl] must be an associative array. Found string(12) "FOLLOW_INPUT"
\[Settings]\[OutputGroups]\[0]\[Outputs]\[0]\[AudioDescriptions]\[LanguageCodeControl] must be an associative array. Found string(12) "FOLLOW_INPUT"
\[Settings]\[OutputGroups]\[0]\[Outputs]\[1]\[AudioDescriptions]\[AudioTypeControl] must be an associative array. Found string(12) "FOLLOW_INPUT"
\[Settings]\[OutputGroups]\[0]\[Outputs]\[1]\[AudioDescriptions]\[LanguageCodeControl] must be an associative array. Found string(12) "FOLLOW_INPUT"

Not sure what's going on here, I've checked my job settings against the documentation and from everything I can find, these should actually be a string, and "FOLLOW_OUTPUT" should be one of the enumerated values. Does anyone know why this error would trigger?
