Markers Track--Can't Change Name

I used an existing project as a template for a new project by saving the project under a different file name (I did not create a Cubase template.). The markers track still shows the name of the old project. If I double-click on the track name in the inspector, the field allows me to enter a new name. However, when I press return, the name on the markers track reverts to the old name. I’ve tried deleting and re-adding the markers track, but the old project name is still there. I cannot find another reference to a project name in the project.
