Every time I try to write something like {age in years}, it converts it to be age%epsilon years. How to change it, is it a bug? If it is a bug someone report it.
in is a keyword in Math for “in set”. If you need some free-form text, enclose it into quotes: "{age in years}".
This is not a bug. But regarding your words
If it is a bug someone report it
please don’t hesitate to report your own bugs. No other is interested to do that.
Thank you, good sir.
