Opportunity "Net Annualized Amount" issue

Hi all,

One of my sales rep updated the Purchase price of the of a product within Opportunity Product Revenue related list. But the changes weren't reflected on the Net Annualized amount on the opportunity.

Let me know if you have a fix for it?

I have tried the users actions on staging and the "Net Annualized Amount" gets updated. But When I tried the same action in production, net annualized amount doesn't get updated. Only the purchase price on the Opportunity Product revenue line items gets updated.
