When I select the font to edit I have problems with the line-height, it auto determines the measurement.
It looks like you may have the same problem as in this thread. It affects text that has been transformed:
If so, it is a bug that has been acknowledged and the following workaround should get you going.
a. Enter the leading value in the Properties panel.
b. When you hit enter the value in the properties panel box will change to something different (that is a bug) but will now show correctly in the Character panel
c. The value applied to the text will be the same as you entered and now shown in the character panel
Note : The workaround does not work backwards - you must enter in the properties box.
