Configurable variations not showing on both frontend and backend but those data are available in database

I have imported the configurable product along with its variations and they have imported successfully.

When I edit that configurable product on the admin, the respective configurable variations are not showing.

I exported that configurable product but on the export file I see the configurable variations value as

“sku=REBF9BILLET-ARB-35-PH,warehouse=Phoenix AZ|sku=REBF9BILLET-ARB-35-WJ,warehouse=West Jordan Utah|sku=REBF9BILLET-ARB-35-ATL,warehouse=Atlanta GA|sku=REBF9BILLET-ARB-35-CSH,warehouse=Cashmere WA|sku=REBF9BILLET-ARB-35-BO,warehouse=Back Order”

and configurable_variation_labels as “warehouse=Warehouse Location”

I have checked in the database as well but those variations are correctly mapped

I have reindex and cleared all the varnish and magento caches but still I don’t know why the configurable variations are not showing under configurable product.

Kindly help me to fix this issue. Your help will mean a lot. Thanks in advance
