I have multiple CSV files, each with a different product brand, the keyImageID is the products item code and any extra images have A,B,C,etc at the end, all CSV files work fine independently, but not together, which doesn't make sense since we don't have duplicate item codes, when i have them all together i am receiving the following error: Error whilst trying to obtain Product Image data from the Generic1 Adaptoradaptor's CSV File data source. An item with the same key has already been added. In an attempt to find the error I have merged all data into one big spreadsheet and i have also checked for double ups in each individual CSV and cannot find the duplicate? is there anyway of finding or being told which entry is the duplicate?
