Spotlight search and dictionary app bug.

I have a consistent problem with spotlight searching and the Dictionary app.

When I try to find a term, e.g. "chair", in Spotlight, I can click on it (or hit enter) to open the Dictionary app. But then the app reports an error:

“Oxford Dictionary of English” is not available in the current dictionary set.

You can turn on “Oxford Dictionary of English” in this application's preferences.

I don't have this dictionary switched on, but switching it on gives a similar error for a different dictionary:

“牛津英汉汉英词典” is not available in the current dictionary set.

Also the preview inside the Spotlight app shows strange output:

"chair|tʃeə(r)|A.noun①(seat)(with no arms and unupholstered)椅子 yǐzi (with arms and upholstered)单人沙发 dānrén shāfā to sit on/in a chair坐在椅子上/单人沙发里

"

It seems to be searching in the wrong dictionary?

I have tried rebuilding spotlight index, switching on and off all dictionaries, but nothing resolved the issue so far

I'm on OS X El Capitan 10.11.1 Public Beta but had the same problem in 10.11.0, that's why I tried the beta. I already submitted a report to Apple.
