Trouble removing extended tag

[bigcitydealer]

I'm trying to remove an extended tag
Action - Remove Fields
The metadata is this:

WWW <DIGITE AQUI A DESCRIÇÃO>

I can't get it to work

The action "Remove fields" remove any field of the given type - but not one with a particular contents.
So to remove all fields of the type WWW in all the selected files use:

If you want to apply that action only to files that have special data in a field, apply a filter first:
www HAS digite aqui

Alternatively, instead of the action, open the extended tags dialogue as described here:

Batch remove extended tags

Load the files Select the files Open the extended tags dialogue Alt-T Select the field that you want to delete and click on the red x. Click OK to apply the changes. Repeat that for every field that you want to remove.
