Fingering doesn't show on a tab only staff

Fingering doesn’t show on a tab only staff and I have “Show fingering” ticked in Layout Options.

I meant to say this is in 3.5 Pro.

I don’t know how this works in Dorico but I’m not sure I’ve ever seen fingering in TAB.

Could you try inputting as text above or below the staff?

Yeah, using text works.
