Followed you video steps exactly and not getting this problem. Mac OS X 10.11.4 Lr 2015.5. I would try resetting your preference file first as that seems to help problems like this.
As per Bob's advice.
Also note you are running v6.3 (voiced in your video) Suggest you upgrade to 6.5.
I do not see the same problem in CC2015.5 WIndows-10
Thanks Bob. I've been trying to reset my preferences but I can't find anything that says reset.How do you do that?
Thanks Wobertc. When I run the Updater no new updates show up on my creative cloud. Is there really a 6.5 version?
Question- Are you using v6 standalone, or are you a Creative Cloud Subscriber?
Standalone users can download here.- Keeping Lightroom Up-to-Date
CC users should use the Creative Cloud App (on the Apps tab) to check and update Lr.
