The buyer is a sourcer for Eastern Europe so probably makes it his work to trawl through people's listings but I find it hard to imagine that I have made the same mistake twice. I have noticed a Japanese company with terrible customer metrics because they had a numberof spurious £1.00 sales that they just cancelled.
Also, an afterthought, if another seller is selling the item with a vastly inflated postage and you opt to "match price" that could be the reason?

The only option I can provide you is to contact seller support with the ASINs and the SKUs in question to find out when the last update was made on the items, how the update was done and for how much. An order id may also be of help for reference.
I am sorry that I cannot provide further assistance to you but I do hope you find an answer to your question.
Intruiging conundrum - and worrying, hope you get answer to this soon
