I notice that a lot of my sales don't receive the commissions they originally had, after checking through last years reports until now I find a number of sales I had entered the commissions for in my own accounting software had now changed, sometimes only small like for example a commission I had for $10 would be now listed as $8 etc, I noticed quite a lot of these from a number of merchants.

Another thing is I noted a number of transactions with commissions that disappear, last week for example I had a sale listed for Brushstrokes Fine Art & the commission was $34, I now look through and found something about a duplicate order in red & in another report it says "Corrected" in red? What is this all about, I never received a duplicate commission, in fact it looks like I get zero so who got the commission?
