Player names not displayed

Hello I opened a lead sheet project from Dorico , but no player/instrument names are displayed ? Why that I thought it is done automatically? Thanx for an advice

The lead sheet template turns off instrument names by default, on the expectation that you’re only going to have one instrument showing in the score.

You can turn them on (for the first system and/or subsequent systems) at Layout Options > Staves and Systems. You can also choose to show them from any System Break or Frame Break, using the Staff Labels property.

Thank you!
