Hiding instrument names

Hello Dorico forum, I imported a score from .sib via musicxml. I want to have it without instrument names. I duly deleted them in Setup>Players panel, but now they are numbered 1 and 2, and I cannot seem to get rid of these numbers (see pic).


How can I get rid of this? Is there a global option to hide instrument names?
