Set custom min/step not working

Hi! I am trying to use this code:

function custom_minimum_order_quantity( $minimum, $product ) {
  // Check if the product has the tag "zestaw-4"
  if ( has_term( 'zestaw-4', 'product_tag', $product->get_id() ) ) {
    // Set the minimum order quantity to 4
    $minimum = 4;
  }
  // Return the minimum order quantity
  return $minimum;
}
add_filter( 'woocommerce_quantity_input_min', 'custom_minimum_order_quantity', 10, 2 );

function custom_quantity_input_step( $step, $product ) {
  // Check if the product has the tag "zestaw-4"
  if ( has_term( 'zestaw-4', 'product_tag', $product->get_id() ) ) {
    // Set the step to 4 (only allow quantities that are multiples of 4)
    $step = 4;
  }
  // Return the step
  return $step;
}
add_filter( 'woocommerce_quantity_input_step', 'custom_quantity_input_step', 10, 2 );

The min is set to 1:

<input type="number" id="quantity_643803d8395e5" class="input-text qty text" name="quantity" value="4" title="Ilość" size="4" min="1" max="" step="4" placeholder="" inputmode="numeric" autocomplete="off">

I’ve tried it on the other theme and it works:

<input type="number" id="quantity_643806f026882" class="input-text qty text" name="quantity" value="8" title="Ilość" size="4" min="4" max="100" step="4" placeholder="" inputmode="numeric" autocomplete="off">

Is GP altering it in any way?
