I can see there is a locked thread 3 months ago with the same error I am getting, it seems there has been no resolution to the software issue.

I tried splitting my shipment into 4 groups to get a packing discount a couple of weeks ago - kept getting "1 Error- this item must be removed". Seller support were obviously no help - the usual, try a different browser etc. I gave up and packed it into one box as usual which worked fine, clearly no problem with my packed items. Annoying though, for the extra time I had spent separating the contents.

Last week I gave splitting the shipment another go and no problem at all.

Today I'm back to the same error - this item must be removed. Which item??? There is no clue. Again I have wasted time splitting the contents.

@Spencer_AmazonI can see you were looking into other cases a couple of months ago - any ideas?

Anybody else managed to solve this issue?
