When CurrencyFormat is set to "FR" and you are manually adding a copier fee or similar to a patron account, the amount will show up with a decimal comma instead of a decimal dot, which won't work correctly.

This is because we are missing the on_editing => 1 filter here:

maninvoice.tt

    <script>
        var type_fees = {};
        [% FOREACH debit_type IN debit_types %]
            type_fees['[% debit_type.code | html %]'] = "[% IF debit_type.default_amount %][% debit_type.default_amount | $Price %][% END %]";
