Can't Use Changing Table When Changing Infants and Toddlers

Hello, 

After the update today, my sims are unable to change the diapers of infants on changing tables. The adult sim says there is something in the way or they can't get to it! I have tried moving the changing table, placing it everywhere on the lot with nothing around it, I have also tried using a different lot and it still is not working. Thank you for your time! Hope it's a quick fix! :)
