Magento 2 Attribute Not Show In Navigation

Question

I have a problem when applying magento 2.1.9 to my project.

My attribute is ab_size

I have created that attribute with code blow.

$categorySetup = $this->categorySetupFactory->create(['setup' => $setup]);
        $entityTypeId = $categorySetup->getEntityTypeId(\Magento\Catalog\Model\Product::ENTITY);

        foreach ($singleAttributeCodes as $key => $label) {
            $categorySetup->removeAttribute($entityTypeId, $key);
            $categorySetup->addAttribute(
                $entityTypeId,
                $key,
                [
                    'type' => 'varchar',
                    'label' => $label,
                    'input' => 'select',
                    'required' => false,
                    'sort_order' => $sortOrder,
                    'visible' => true,
                    'user_defined' => true,
                    'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,
                    'filterable' => 0,
                    'visible_on_front' => true,
                    'used_in_product_listing' => true,
                    'group' => $group,
                    'apply_to' => 'simple,configurable,bundle,downloadable,grouped',
                ]
            );
        }

With config in the backend.

1. Enable filter (with result) done
2. Category Is Anchor done
3. Reindex done
4. Enable Category flat done
5. Enable Product flat done
6. Reindex all data done
7. Clear cache done
8. Use magento clean doesn't have any extension done
9. Check with attribute color (done it show in navigation)
10. Product Price Show

11. Category Show

    about my system information

12. CentOS 7.0

13. Litespeed
14. Php7.0
15. Magento CE 2.1.9

I have debugged that the product collection buckets return empty

I think that problem with creating attribute code, has anyone got the same problem.

Thank anyone have tips.
