Troubleshooting AI Column Array Reference Issues in JSON Output

I am running an AI column that is referencing an array item outputted from another AI column. The list is outputted as an array, as specified in the json output formatting and in the results it appears as an array with separate items. However, the second AI column keeps saying 'run conditions not met' and the explanation is that it is text instead of an array. I am 100% sure I reference the correct data point, and that it is an array. How do I fix this?
