Extended CPTs issue in Radicle

I’m using an instance of Radicle (1.4.0) with Sage, Trellis via Lima on a Mac and trying to register a new taxonomy via Extended CPTs (5.0.8):


'device_category' => [
            'public' => true,
            'show_ui' => true,
            'hierarchical' => true,
            'query_var' => true,
            'post_types' => ['device'],
            'required' => true,
            'allow_hierarchy' => true,
            'exclusive' => false,
            'meta_box' => null,
            'names' => [
                'singular' => 'Device category',
                'plural' => 'Device categories',
            ],

When using ‘’meta_box’ => null it should display the default WP metabox. However it’s simply not being displayed anymore. Other values, such as ‘simple’ or ‘dropdown’ work fine, just not the default one - null.

Changing the ‘exclusive’ value seems to display the ‘simple’ meta_box type.

Is this related to Radicle or Extended CPTs?
Could maybe someone test just to make sure it’s not something on my end?

Thanks in advance!
