Grace notes not working

I’m trying to add grace notes. This is what happens after I select the notes and

click the grace note button:

Assuming you wanted a grace note before the half note, you should activate the input Caret and then choose the grace note option and the duration value before entering a pitch (unless you have pitch-before-duration mode on).

What is the input caret?

It’s the orange line that appears (when you press enter in your case above to start note entry)

So the steps are. Select your note, press enter, select grace notes (/) , enter your grace notes.

Thanks. I was doing it wrong.
