TYPO3 Core

I want to add a description to the corresponding items of the selectCheckBox input type. If i proceed like in the doku ref. (see here: https://docs.typo3.org/m/typo3/reference-tca/10.4/en-us/ColumnsConfig/Type/selectCheckBox.html#items ), then the output is somehow grouped.

Here my minimal reproduction snippet (add it somewhere in a tca php file):

'column' => [
    'exclude' => true,
    'label' => 'test title',
    'description' => 'test descr',
    'config' => [
        'type' => 'select',
        'renderType' => 'selectCheckBox',
        'items' => [
            [
                'item title 1',
                '1',
                '',
                'item desc 1',
            ],
            [
                'item title 2',
                '2',
                '',
                'item desc 2',
            ],
        ],
    ],
],

Preview:

if i insert a null on the 4th position, then the grouping bug is fixed, but no description is shown.

[
    'item title 1',
    '1',
    '',
    null,
    'item desc 1',
],

i think it has to do with this:
