Data not changing on frontend for variable products

Hi. Great plugin!

I a m using WP All Import for creating and updating data, and everything working great, strings are updated with new data, but frontend shows old data for variable products (prices, promotion start/end dates, etc).

At the same time if I’m saving variation at backend, everything goes back to normal and frontend showing correct, updated data.

Can you tell me is there any additional action or function I need to run to trigger changes on frontend?
