If you need to un-import a page for any reason, you can easily do so by using the "Revert Import" option in Shogun.
Undo an Import From The Shogun Dashboard
To reverse a page that has been imported into Shogun, first, you can locate the page in your Shogun dashboard.
Click the three-dot Settings button, and select the "Revert Import" option.
This option will:
Remove any Shogun content from the page
Restore the content that was in place prior to the import
Remove the page from your Shogun dashboard
Note: This process will not delete the page from your store. After the import has been undone, the page will still exist in your store's catalogue.
