Stores not importing correctly with CSVImporter

I am using the csvImporter plugin with CouponPress (though the specific PREMIUMPRESS package is irrelevant) and I am trying to get the stores to import using a “store” field in the CSV file.

Should be simple enough, but at the moment the store gets imported as a custom field called “store” rather than being linked up with the relevant store that has already been created in the taxonomies.

The category works perfectly.

If anyone wants to see the problem, I will attach the CSV file below which shows the store being imported as a custom field rather thna being attached to the approapiate store.
