Item deletion and smelting workbench bug

In the process of transferring a character from solo mode to standard, all the items and goods in the warehouse were lost. When transferring a character, the transfer of all information did not appear, but only the transfer button was activated, so I proceeded like that, but that seems to be the problem. Please take action. (Restore items) Additionally, the smelting bench has disappeared. What kind of bug is this??
