On the top, right above where it says inventory, do you have "yes" selected under show categories? If so, change back to no. I was searching for the board (which is unfortunately old meaning that this has been an issue for a while). Feel free to post there that you are still experiencing this. ! Locked item issues when showing categories

Otherwise, if that does not fix it, then yes file a ticket because I can see the items in your inventory.

It is still definitely a bug...just one with a workaround! I would post on the board I linked just so we don't have duplicate reports but it is a bug.
