I downloaded CotEditor Version 3.3.0-beta (216) and I have a problem with
_Syntax Style_ always shows _None_ for any file I open.
I restarted my Mac, and re-downloaded it, and still having this issue.

Hmmm, thanks for opening an issue.
Could you tell me your macOS version?
Ah, I've just reproduced this issue.
This is definitely a bug caused by my mistake. Sorry.
I'll fix this in the next beta, 3.0.0-beta.2.
Thanks.
I've just released CotEditor 3.3.0-beta.2 fixing this issue.
OK, I updated the version (3.3.0-beta.2), and it is showing Syntax Style 👍
@bluemix Thank you for confirming the bug fix.
