Problem: The client wants to display only the non-active language in the WPML Language Switcher Block within a block-based menu using the twentytwentyfour Theme, but cannot find the setting to achieve this. Solution: Currently, it is not supported to hide the current language in the Language Switcher block. This feature has been requested and the client's ticket has been linked to the feature request for additional support.
