When setting the frame grid with the shortcut key, it becomes an unintended font display
InDesign Ver.13.0.1 x64(CC 2018) Japanese Edition
1. make new document
2. make new frame grid
3. select frame grid
4. press key "Ctrl+B", and open dialog
A font that starts with "B" installed in the system is displayed in the font setting of the dialog.
Should be displayed is the default "Kozuka Mincho Pr6 N".
CC 2017 and older versions are no problem.
Thanks for reporting the issue. We will look into this
It appears with Windows InDesign CC2015 Japanese Edition.
