I am using SharePoint 2013 on premise. A site administrator moved a subsite to a different site collection in the same web application. However, the link to this subsite is still showing up in the structural navigation of the original site. I tried to manually delete it: go to Site Settings-> Navigation Settings, the link is not shown in the Structural Navigation: Editing and Sorting tab.
Is there any way to get rid of that link in the structured navigation? Is it maybe cached? Any help would really appreciated. Thanks!
