Duplicate View of Contributions

When creating a soft credit for a fundraiser, if you then modify the transaction adding a a PCP credit on the same transaction, the transaction is shown twice in the soft credit section of the contact record. See screenshot attached:

To reproduce per demo site:
1) Open a individual user (I used Teresa Blackwell)
2) Create a donation, soft credit to someone (I used Alexia Terry)
3) Look at Alexia Terry's contribution record, you will see 1 soft credit - i.e. the one created above.
4) Go back to the original contribution by Teresa Blackwell, and edit it, and set the PCP page to be Alexia Terry's page.
5) You'll now see two of the same transaction - one showing the PCP page, one showing N/A. A quick mouseover shows the transaction ID for both to be the same.
