Also if I do this manually then it is created after that if we take export pack of [RF_PRODUCT_FEATURE_VALUES] then this is coming

[RF_PRODUCT_FEATURE_VALUES] !PRODUCTID!PRODUCTCODE !PRODUCT !CLASS !OPTION !VALUE

If this is coming in export pack then why I cannot able to import them?

That's how it's made. Same with orders you can export them but not import.
