internal link between invoice and payment lots

[Edward Hardy]

Hi there

I am quite new to Gnucash, and just updated from 2.4. to 2.6. I am 
having a simple issue when paying an invoice. When I create the payment, 
instead of seeing one extra row in the Receivables register, I am see an 
extra 3. These are:

- The one payment row I expected
- A new invoice row, with memo "internal link between invoice and 
payment lots"
  - A new payment row, also with memo "internal link between invoice and 
payment lots"

This means I now have a total of 4 rows, whereas before (in version 2.4) 
there were only 2. I assume they are there to show the link between the 
invoice and the payment, but it isn't half cluttering up the register.

Is there anything I can do remove these additional rows, or stop them 
being created in the first place.

Thanks in advance,

Edward
