Comma (etc.) full

Hello,
Little question: After designing my comma, slash, asterisk, etc. Glyphs duplicate them with .full behind the name. So: comma.full, slash.full, asterisk.full, etc.
What is the use of this?
Greetz

they are useful in CJK font

So, I can delete them? My font will be Central and West European.

sure

When did Glyphs added the .full glyphs?

I am not shure. Maybe after I finished the comma, slash, etc.

Never happened to me that the software added these glyphs by itself. If you can reproduce this phenomenon, please let us know how.
