Not sure what you mean.. We do not have shipment to PBAT last week.
The unit you brought over should follow next shipment to PBAT if any, together with the cracked end over.
Please note the cracked end cover did not impact the performance, and the material of customized end cover is very soft caused end cover easy to crack during dismantling.
There should be 2 units.
We swapped the lock nuts.
Please check.
