Upgrade XBMC 13 to Kodi 16, Video Queuing Takes Long Time

I upgraded XBMC 13 to Kodi 16. After I did so, it now takes a very long time to queue up videos from the library. Previously I was able to queue 10-15 long seasons of a TV series (20-26 episodes per season) in only a few seconds, but now it can take a full minute or more just to queue a single short season (10-15 episodes). Queuing multiple seasons, especially long seasons, takes a ridiculously long amount of time. Is there any way to resolve this?
