Private label product showing inactive/unavailable following changes after requesting support as product was unsearchable on Amazon.

Hi Guys and ladies, has anyone experienced their private label product showing inactive/unavailable when you have hundreds in stock. Products were available in hundreds before change made following support request for product not searchable on Amazon.

Advised to delete and relist but I am scared of deleting and relisting as it took me ages to list the first time I did so.

Kindly help
