Hi there 
I don’t know why but when I want to press my character styles on the right hand menu to edit my leading and kerning or to change transparency its not allowing me to click on these features ? 

Can someone please help 
Thanks 🙂

Can you elaborate a bit?

Are the character styles greyed out? Or something else?

Show please a screenshot with the object selected, Character Styles panel open, and the right-hand menu expanded.
