Why are there hidden Web Parts?
There are two reasons why you may have hidden Web Parts on your page:
One is that you deleted a ShortPoint Design Element that contains a Web Part.
Another is that you deleted the Web Part using the Edit Source button from SharePoint.
How to check hidden Web Parts?
Follow the steps below to learn how to check if your SharePoint page has any hidden Web Parts:

Once the Web Part Page Maintenance Mode is opened, it will show you a list of all Web Parts running on the page, including those that you do not see (Hidden Web Parts).

Step 4: Delete Hidden Web Parts
Select the hidden Web Parts and click Delete.
In our example, we see two Documents Web Parts. Since we do not know which one is the hidden Web Part that needs to be removed, we will select them both and delete them.
Then, click Go Back to Web Part Page to add the Documents Web Part back:
