renaming folder doesn't change url of the document

First time posting!!!!

We had a folder named ORDERS under our home SharePoint under the Shared Documents folder.

We changed the name of the folder from ORDERS to ZURN and now when we search from the home page for an item that was originally saved under the ORDERS folder, the search finds the document but the link is still showing the ORDERS folder and it won't bring the pdf file up for viewing.

How can we change all the documents that was saved under the ORDERS folder to be able to display if the location is now under the ZURN folder?

example:

document won't launch

https://xxxx.sharepoint.com/Shared%20Documents/ORDERS/SO%2016211370.pdf?web=1

document will launch

https://xxxx.sharepoint.com/Shared%20Documents/ZURN/SO%2016211370.pdf?web=1
