Description 1 field on P4314 Match Voucher to Open Receipt Screen

When our AP members enter a 3-way voucher match via P4314 Match Voucher to Open Receipt program, they are unable to manually type in the description they desire under Description 1 field if they create a new orderline (OP field = 4). Instead, the description under Description 1 appears to be the description of the account number they enter. In the example below, the AP clerk was able to manually enter a description under Description 2 field, but Description 1 field would always default to be the description of the Expense
Account Number they enter. Is there a way to change the setting so we can manually enter and save the description under Description 1?
