this is a long time bug. After updating an order invoice in ebay site, GS doubles the order and keeps both copies, the updated one and the older one. What’s worse, it not only doubles the order. When the order is paid, one copy is shown between paid orders, while the other one remains between not paid ones. This is a problem, because it seems buyers still didn’t pay, but actually he did and I already shipped. I expected the “shipped” or the “paid” flags would delete the not updated copy, but actually they don’t. One copy of the order remains in GS and I have to manually delete it.
I reported this bug at least during last two or three years. Sure last during this period and it wasn’t fix, because I remember I spent time every night deleting doubled orders. My last quarter of the year is the most busy in ebay and I loose much time checking orders one by one if they are doubled or not. Is there any possible fix? I hope so…
