Cost coming from the wrong branch plant?

We have a scenario where we have an item that is sold across several different branches, each of them having a different standard cost.

In the example below, the only item on the purchase order that is sold out of a different branch is the only one that has a different standard cost.  All of the other items are only sold out of a single branch plant and are showing the correct Standard Cost.

When I look at the F4105, the price that is showing up in the Standard Cost field, is the cost associated with Branch Plant 1101, and it should be 1501.
