Wrong error on team option "nametagvisibility"

Command: [/scoreboard teams option <team> nametagVisibility]
Error: [Valid values for option nametagvisibility are: true and false]

Probably just a language problem, just like MC-48419 (AKA tile.ironTrapdoor.name, btw, there are about 8 bugs posted about this one.)
(don't care about the [] brackets, it just looks a little better this way)
