End Temporary Assignment Action not working in Redwood

Navigation: My Client Groups > Show More > Change Assignment > Select "End Temporary Assignment" and the continue button will not move forward to the next section. It also does not give any error message to give insight into what is preventing it from moving forward.

Has anyone else experienced this? It is on an employee's secondary assignment, so end temporary assignment should be an option, the other actions will move to the next selection when selected, so it seems to be specific to "End Temporary Assignment".
