AVEVA InTouch problems with deleting tags

I'm having trouble deleting a tag in AVEVA InTouch. I know the procedure of looking at cross references and finding where the tag is used, but this tag is referenced in a non-existent window? The window MS-HydMain does not exist. Is there a possibility that this is automatically generated window or something like that?

I attached a screenshot of the tag in question in the cross reference tool.


Try searching the project explorer for the window name MS-HydMain, deleting the tag directly from the project explorer, and then utilize the InTouch Find and Replace feature to locate and remove all references to the tag MS-HydMain.
