Conditional Logic Not Working

Hey Guys,

I am having a bit of a hard time with the conditional logic on a couple of fields...
It seems it works perfectly on all others though, So I can't figure out what I am doing wrong...

Can you please advise?

The code added to the fields are as follows:

array(
                'id' => 'certified-load-capacity-of-concrete-floor-slab-fill-in',
                'name' => 'Certified load capacity of concrete floor SLAB',
                'type' => 'number',
                'step' => '0.01',
                'columns' => 6,
                'tab'   =>  'site_assessment_of_the_data_center_location_2',
                'visible' => array(
                    'when' =>
                    array(
                        array(
                            0 => 'certified-load-capacity-of-concrete-floor-slab',
                            1 => '!=',
                            2 => 'N/A',
                        ),
                        array(
                            0 => 'certified-load-capacity-of-concrete-floor-slab',
                            1 => '!=',
                            2 => 'Unknown',
                        ),
                    ),
                    'relation' => 'and',
                )
            ),
            array(
                'id' => 'certified-load-capacity-of-concrete-floor-slab',
                'name' => 'Certified load capacity of concrete floor SLAB',
                'type' => 'radio',
                'options' => [
                    'Kg/m2' =>  'Kg/m2',
                    'Lbs/ft2'   =>  'Lbs/ft2',
                    'N/A'   =>  'N/A',
                    'Unknown'   =>  'Unknown'
                ],
                'inline' => 1,
                'columns' => 6,
                'tab'   =>  'site_assessment_of_the_data_center_location_2'
            )

Basically the text input just remains visible no matter what option is chosen... Not sure what is causing it though... any way to debug?
