Button Links URLs stopped working after WordPress 4.2 update. Unable to edit them.

Hi,

Love the Boldial WordPress theme but suddenly the button linking is not working. It’s worked in the past. When you click on Add URL, you can go select the URL but it doesn’t take. The only thing I can think is that recently there was a WordPress update. Buttons I added previously to the update are still there, but I cannot change them or add new ones.
