Other Payment in Payments Journal not letting me enter an amount.

SOLVED

I've recently taken over the bookkeeping for a small hotel.  When I started, whenever I needed to write a cheque to the owner, I did so through the payments journal, using the "Make other payment" option, which worked absolutely fine. 

A couple of days ago, the space to enter the amount of the payment disappeared.  It doesn't matter how I try to pay, whether by cash, cheque, direct debit or ccd, there is nowhere to enter an amount.

My work around for this is to create an invoice, then pay it in the payments journal under 'pay purchase invoices', but it's a weird and tedious way to things, so if anyone has an ideas on how to do it better, they would be much appreciated.

Thanks in advance.
