How to I remove duplicates from the tag list ?

[Martin B.]

When I use dbpoweramp to edit a file or multiple files and I click the Add button to add a tag, a list of tags appear.
However I have several duplicates on the list, and a tag I added to the tag txt file doesn't show.
I'm currently assuming that it doesn't show as there is no space on the list, but how do I remove the duplicate "Composer Sort", "Conductor Sort", SoloistsSort" and "Title Sort" from the list.

This is a relatively recent clean install on a new PC.

Open windows file explorer and type:

%appdata%\dbpoweramp

and it should be listed under:

DefaultTagEdit.txt
