Negative on-hand Inventory quantities or items received without a bill

Hi - when I try to lock a period (in this case - 1st July 2024) I am getting the message screenshotted on the attached.  I can see this has been asked a few times before in this forum and I have tried the suggestions that have been provided.  I have run numerous reports and cannot see any negative on-hand items.  There are however, 2 with an negative on-hand value of just -$3 and 1 with a -$.01  These have been screenshotted on the attached.  I have also looked at the Purchase Register to see if stock on an order has been received.  This is the case for an order dated 25th July but I am trying to lock the period prior to 1st July.  Would this be causing the issue?  A screen shot is included on the attachment. The Order that has been received is a completely different inventory item to those with the negative value.  How do I find the offending inventory item and then how do I fix it?  Thank you
