The user needs to resolve an issue where two different list entries in SharePoint Site Contents share the identical URL and list GUID.

How to Fix SharePoint Showing Two Lists with the Same URL and GUID

Product: SharePoint Online / SharePoint Designer 2013
Device & OS: not provided
Scenario: Navigating Site Contents or modifying list URLs in SharePoint Designer.
Observed behavior: Duplicate lists appear with the same URL and GUID. Renaming the URL of one list redirects to the other list's URL, and web browser views continue to display the incorrect, duplicated address.

Before you start

Before proceeding, ensure you have sufficient administrative permissions in SharePoint Online and have safely backed up all important list data.

Solution 1Recommended

Migrate List Data and Clear SharePoint Designer Caches

This solution involves transferring data to a clean list and completely purging the stale SharePoint Designer cache that is causing the duplicate GUID conflict.

Duplicate GUIDs and URLs usually stem from incorrectly created lists or corrupted metadata inside SharePoint Designer 2013. Directly deleting one often impacts both. Migrating the data safely to a new list is the most reliable fix.

Create a replacement list

Log into your SharePoint Online site, navigate to Site Contents, and create a brand new list configured with the exact same columns as your affected lists.

Import list data via Power Automate

Open Microsoft Power Automate and set up a flow to extract all data records from the affected duplicate list, then route and import that data into your newly created list.

Remove the duplicate lists

Once you have validated that all list items have been copied successfully, delete the conflicting duplicate lists from both SharePoint Online and SharePoint Designer 2013.

Clear local SharePoint Designer caches

Close SharePoint Designer 2013 completely. On your computer, navigate to and delete the contents of these three folders: %USERPROFILE%\AppData\Local\Microsoft\WebsiteCache, %USERPROFILE%\AppData\Roaming\Microsoft\SharePoint Designer\ProxyAssemblyCache, and %USERPROFILE%\AppData\Roaming\Microsoft\Web Server Extensions\Cache.

Clear browser cache and verify

Clear your web browser's cache and cookies. Sign back into SharePoint Online to confirm the duplicate lists are gone and the new list is functioning correctly.

Migrate List Data and Clear SharePoint Designer Caches

Data Loss Prevention: Do not delete the affected duplicate lists until you have thoroughly verified that Power Automate has successfully migrated all records to your replacement list.

Frequently Asked Questions

What causes two SharePoint lists to share the same URL and GUID?

This issue is typically caused by corrupted metadata on the SharePoint server, stale local cache data in SharePoint Designer 2013, or a glitch when duplicating list templates during site customization.

Why doesn't renaming the list URL fix the duplication?

Because the underlying list GUIDs are identical, SharePoint's backend routing continues to redirect the renamed URL back to the original list's properties. Your browser or Designer cache also continues to serve the outdated, duplicated URL.

Where are the SharePoint Designer 2013 cache folders located?

The primary cache directories are located on Windows at %USERPROFILE%\AppData\Local\Microsoft\WebsiteCache, %USERPROFILE%\AppData\Roaming\Microsoft\SharePoint Designer\ProxyAssemblyCache, and %USERPROFILE%\AppData\Roaming\Microsoft\Web Server Extensions\Cache.
