There is a bug that has been persistent for a long time and it is that it does not allow the pricecharting id to be deleted, something necessary especially when it is incorrect. Sometimes it also does not allow it to be replaced by another one.
I do not know if this problem stems from the usual fact that users have made mistakes in the past when adding new items to the core, and then the Windows application puts incorrect information from the core before new information verified by ourselves, as usually happens with barcodes to which incorrect titles are assigned.
