Hi Robert
Is it possible that these duplicates existed before syncing? I had the following problems and I DO NOT use syncing.
This was not resolved by GS Help. Because of corruption in my database, I have had to completely rebuild my database from scratch using Import from Ebay. I have been working on this for a month and I am nowhere close to finishing- about 27,000 items. I have also lost all of my previous order information prior to November 2020.
I am not happy about having to do this but as GS Help seemed unable to solve my issues, I just had to be proactive & take the plunge.
