Fixed Recently sold "Player Service" trade is deleted when you mark as sold another "Player Service" trade

Hi

Happened to me twice...
the first time happened a couple of days ago and I thought at that moment that I deleted the trade by mistake... but I'm sure that I didn't deleted the trade on the second time... so it seems like a bug....
(as "Player Services" trades behaves differently in some scenarios... - don't have a "Mark as Sold" button for example, you need to Edit to mark them as sold)

The second time happened a few minutes ago.

Around 5 hours ago, I marked the trade trade/10-mm-gold-t1580845.html as sold (a "Player Services" trade), the other user even gave me Trust.
(and it appeared on my "Recently sold" list)

And a few minutes ago I marked the trade trade/10-mm-gold-t1580106.html as sold (a "Player Services" trade too).

When I entered on my "Recently sold" list, the the old "Player Services" trade was missing , and when I clicked on the link (I had it saved), I confirmed that it was deleted

Additional info: Both trades are similar, they had the same title "10 MM Gold", description "Offer 5
