Cannot change fingering font

Hello
I cannot change the fingering font in a project. Any font other than bravura displays as squares instead of numbers.
Any thoughts?
Thanks

See Daniels answer down below

Oh I see! Thanks! But are there more SMuFL-compliant fonts, and which ones, that come with dorico so that I can choose?

You don’t have to use a SMuFL-compliant font for fingering. On the Fingering page of Engraving Options is an option to use a ‘Plain font’ for fingering. Once you have chosen that, you can edit the ‘Fingering plain text font’ in Engrave > Font Styles to use whatever font you would like.

Well, it is great to learn something every day!
I edit my post accordingly
