Associate csv uploaded to MDA with salesforce account via id

I have a simple csv with 2 columns, a renewal prediction (boolean 0 or 1), and a salesforce ID. I've uploaded this spreadsheet to a matrix data object and I thought I did what I needed to to associate the prediction with the appropriate account via the ID per the below:

However, I'm trying to build a report with this data to prove the association is working and it does not appear that the renewal prediction score knows what account it is associated with. When I try to build a report with the prediction value and the parent account name, all the account names are blank. Am I missing a step? I confirmed the IDs I'm working with are correct.
