Can't name items in 20w10a

You can't rename an item in an anvil in 20w10a. This may be due to it being an experimental version, but as someone who likes playing in snapshots and likes to give funny names to my tools, this is a big inconvenience. This is made worse by not being able to go to a different version to rename my items in my survival world. If this has already been reported, I am sorry for wasting time, but I did search about a minute under "20w10a" and "naming". Thank you and have a great day 🙂.
