[Bug] combo_should_trigger doesn't activate for any layer.

Describe the Bug

This is my combo.c that doesn't work.

bool combo_should_trigger(uint16_t combo_index, combo_t *combo, uint16_t keycode, keyrecord_t *record) {
    /* Enable ARTSEY combos on layer `_ARTSEY` */
    switch (combo_index) {
#if defined(ARTSEY_ENABLE) && !defined(NO_ACTION_ONESHOT)
        case ARTSEY_B ... ARTSEY_EXLM:
            return layer_state_is(_ARTSEY);

#endif
    }
    return true;
}

I want to only activate those _ARTSEY_* keycodes when _ARTSEY layer is on. But with the code above, none of the layers have those _ARTSEY_* combos.

Additional Context

uint8_t combo_ref_from_layer(uint8_t layer) {
    switch (get_highest_layer(layer_state)) {
        case _ARTSEY:
            return _ARTSEY;
        default:
            return _QWERTY;
    }
    return layer; // important if default is not in case.
}

Also doesn't work for me, but I don't know if it's related
