Product Name change


I am looking to update a name of a product we use. When I complete that, I can see that the changes are made throughout the opportunity’s line item (one product per line). However, I have created a custom entity to track each line item’s schedule of revenue (see example below).

Opportunity 1
–Line Item 1
----Date 1
----Date 2
–Line Item 2
----Date 3
----Date 4

Since Schedule is a 1:N relationship with Line Item, there is a lookup field to the specific line item. However, the lookup field displays the previous product name.

Is there a cache or something that needs to be cleared? Or is there a job that needs to be run in order to complete the cascading name change?

Thanks in advance!
