What OS are you running?
This bug should be fixed in the update that released today. See Tim's post about it here. The After Effects CC 2017 update to version 14.2 is rolling out worldwide. It may take a day or so to show up for you depending on where you live. You also may need to log out and back in to your CC app or other funky things to get it to show up.
Please let us know if this works for you.
