Approval workflow not allowing reassignment anymore. Did something change recently?

I handle reassignments/delegations for our financial approvals (procure-to-pay) and I recently noticed that the way I used to be able to reassign approvals isn't working. A couple things are different. Below are the steps I used to take to reassign an approval, and under it is what happens now when I follow the same steps.

Past (using PO 12345 as example):

1. Open BPM
2. click on Administrative Tasks and search the doc to reassign (i.e. PO 12345). There are 2 rows for each PO; one with just a title, and the other has a + sign next to the Status column
3. click on the row with the + sign
