 ### Fixed
 
 - Fix `TypeError` when accessing `ApplicationCommand.guild_only` or
   `SlashCommandGroup.guild_only` when `contexts` is `None`.
   ([#3320](https://github.com/Pycord-Development/pycord/pull/3320))
+- Fix `option` keyword argument in `Label.set_radio_group()` and
+  `Label.set_checkbox_group()` that caused `TypeError` when used.
+  ([#3337](https://github.com/Pycord-Development/pycord/pull/3337))
 - Fix `SyntaxWarning` about `return` in a `finally` block raised on Python 3.14+
   ([#3332](https://github.com/Pycord-Development/pycord/pull/3334))
