I dont know about this specifically however, using the same thing on Mamazon for years if there is an update like new info needed then you need to download the new format all over fresh and clean, then transfer your details (copy paste columns) then you are able to hand fill-in the newest detail on each listing. Sometimes there is a drop box on each where you can select, sometimes you have to place yours in individually on each. Hope I helped cause all sellers know who does NOT help us. 🙂
