I exported the .csv file and changed several hundred Vmemory locations and want to import the new documentation. However, the current documentation still exists in the program and the "delete existing" option is not deleting all of the current documentation when I import the changed .csv file because it is finding duplicate nicknames on memory locations that are not listed in the new .csv file. I would have thought that when you choose this option, it would have cleaned out all the old documentation on all coils and memory locations regardless. However, this doesn't seem to be the case. Is there an easy way to delete only the element documentation so I can import a clean file?
