Why all of our assets coming from Payables is defaulting in as one Category instead of the category

We are unsure why all of the assets coming from Payables is defaulting to the same category instead of the category selected at time of PO.

Also, when we go to override the assets as we prepare the file to load to Plant Ledger, the values are no longer updating in Plant ledger. The asset retains the value of what defaulted in.

Any direction is welcomed
