I find a solution to the method that should help you bug fixes for your software development.
I also use Glyphs Try Version in the traditional Chinese environment, I did not encounter this problem in the office computer, but the home computer has encountered the same problem, so I found between the two computers in their different settings, Finally found to be in the “time format” caused by the error.
See the picture.
Glyphs can paste the copy from illustrator, as long as you use the “24-hour” format. I do not understand why this will be provided to the developers you reference.
Because it took me all night time, if you can give me a set of free use, I am happy to continue to help find some problems.
