OCA bank import (V17) error: Bad file/mapping: 'Amount' is not in list when 'Distinct debit/credit' selected

[StuartJMackintosh]

Module

OCA/bank-statement-import (V17)

Describe the bug

'Amount' is not in list when 'Distinct debit/credit' selected and no Amount column.

To Reproduce

Create a bank statement file that has distinct debit/credit columns, load and an error is generated

Add a new column 'Amount' which is sum(+debit-credit) and the file loads.

The error suggests that the Amount column is not included however this shouldn't be required as I have set separate debit/credit columns which suggests that Amount is hardcoded somewhere

Expected behavior

I expect that the amount is calculated from debit/credit when this option is selected.
