Cadence Capture 17.2 - Purging blank/duplicate property columns?

[Uky]

Greetings forum.

Using 17.20, I am working on a design that uses schematic symbols copied from various sources. When examining the structure (Select "All" - Right click) - there are a lot of property fields that are either empty or with similar names, such as "MFR" and "Manufacturer". These are not the built-in ones that comes with a new/blank project start but has been added from previous designers that uses the CIS-option.

The examples above are not the only ones. There are "a lot" more duplicates...

When trying to delete these empty columns, I get an error message that basicallys says that the property cannot be deleted because it exists in some of the (schematic) symbols themselves.

Now - Is there a way to select and purge these columns?

I usually get this error, but it does delete the row anyway. I always assumed it was just a minor bug.

(Using 17.4, but IIRC it was just the same in 16.6 and probably earlier versions too).
