Kodi v16.1 – Can not change/set Category

Hi,
I have replace Kodi v15 to Kodi v16 on my MacMini,
After that, something strange things are happen

I can not set (or change) the category on the folder,

1. I select a folder
2. Click right button of mouse
3. Select ‘Set content…” (last menu)
4. I have set Movie (or others)
5. I have set Scrapper (I have tried every one in the list on the right side)
6. OK
7. Kodi ask me to search all include sub-folder
8. I select ‘Yes’

When I came back, there is nothing has been set,

Note. I am using – macOS Sierra
