From your pricing page (price book) select the 3 dots to the right of the service you want to update. In the pop up updated all related fields. These updates once saved will reflect on all configured services. Before saving, do not select "update related all configured service price"
Only select this option if you have changed the price and you want that price reflected on ALL matched configured services. If left unchecked, this option will update the Service name, action, method, etc for the matched services without updating the pricing on the customers profile.
