@LadyGrey18 Does anyone know if this is something that is being enforced in all courts or is it just down to the individual judge?
The judge is acting in accordance with 2018 Bench Book (from @RadFemLawyer on twitter).
"Everyone is entitled to respect for their gender identity regardless of their legal gender status. It is important to respect a person’s gender identity by using appropriate terms of address, names and pronouns."
"It should be possible to recognise a person's gender identity and their present name for nearly all court and tribunal purposes, regardless of whether they have obtained legal recognition of their gender by way of a Gender Recognition Certificate."

It would be worth comparing the previous edition; I do suspect this is a new addition for this edition.
