Clean Library – Freezing

Using Kodi 17.1 on a MacBook pro retina with OSX 10.12.4
When I run kodi, I noticed that since the last upgrade, I had duplicates for every movie in my library. I attempted to run the library cleanup multiple times and at about 33% it totally freezes up. I have re-installed the current version several times hoping it would clear it up, but no luck. I just tried the 17.1 nightly and same thing, but now when I try to exit the program, it locks up again. Last night, I initiated the cleanup just prior to going to bed. I woke up this morning and it was again froze at around 33%.
Any help / suggestions are appreciated.

Is Leia stable yet?

How do I add the log file to my post?
