InDesign VERSION 19.1
I Created a new font using "composite fonts", chose the base font, latin & Numbers. after creating the new font, i selected the text frame and applied the new font i created (like i always did)
the problem is, tha the latin letters showed up with wide spacing (wide tracking) - shown in the attached image.
While teaching my student that, they told me the encountered the same problem. Since i have used it in the past i assume it is a bug
