Showing Tacet

I am new to Dorico and I am loving it! I converted a Finale file I was working on to XML. Once I put it in Dorico, I added a timpani line which went in so easily! When I go to print it, it shows all of the notes on the score but on the individual part, it says “tacet.” Is there something that I did wrong when inputting the notes/part? Thanks for any help!

In Setup mode, click on the Timp layout in the right hand panel, and then make sure the correct players (in the left panel) and flows (in the bottom panel) are selected.
