Auto lip Sync no longer working

Since the update my auto lip sync is not working. Im using a symbol that I've used several times before but when in the visemes selection area it won't open up with the rest of the avalible frames. I know nothing has changed with the symbol because if I open the frame picker window all the positions are there and when I scrub/playback the animation it is cycling through the different positions. It might just be a bug, but i was curious if anyone else has had this issue since the update
