Sharepoint Online Search is finding old folder name

Hello - We have users copying folder structures in a document library, then renaming the main folder. However, when we use the search function on the library, it pulls up the newly named folder when we are searching for the previous folder. For instance, I copied a folder called '11881.00' and renamed it to '21-0486'. That was a while ago. Today, I was searching for the folder called '11881.00' and it brought up the new folder ('21-0486').

According the the properties in the search list, the Title and Name of the folder are different. But when you look at the details in the regular document list (not within the search), both the Title and the Name are correct.

(current folder title/name - I do not want this folder to come up with I search for '11881.00')

(folder that comes up when searching for '11881.00', it shouldn't come up, as the 'Name' is 21-0486 now):

I know this is confusing. But just need the search to not look for other 'versions' of the folders / names or cached information. I'm not sure how to explain it better.

Thanks, in advance.
