Magento 2 Price of configurable is zero on store front

We make an import of CSV with products programmatically and getting prices $0.00 on the storefront for the first time. After some minutes it’s getting normal. I am using Magento 2.2.9 Community Edition. I believe it’s some issue with reindex or something..there are many products and we can’t make full reindex after each import.
