How to use XLD's "import tags from a text [file]" feature

I have a batch of AIFF files I am trying to transcode to mp3 and tag using [XLD](https://tmkk.undo.jp/xld/index_e.html) (X Lossless Decoder). I have all the tag metadata in a text file like so: 01 AUDIO "Package" "Peter Howard" 02 AUDIO "Nirvana" "Martin Figura" 03 AUDIO "Fresh Meat" "Andrea Porter" 04 AUDIO "The Shout" "André Mangeot" … Where that format of each line is: [track number] AUDIO "[track name]" "[Artist]" I'm trying to use the "File > Import Tags From a Text" feature in the following way: 1. File > Open folder as disc (I have all the .aiffs in a folder). 2. File > Import Tags From a Text. 3. Paste in the block of data from above into the main pane. 4. Use the following "Format": %n AUDIO "%t" "%a" (i.e. the same as above) 5. Match with: Track Number. Overwrite existing tags = yes. 6. Select all tracks in the main window. 7. Click Apply. Nothing happens at this point, but I don't know if I've got the format string wrong, or if I'm using the whole feature incorrectly. There isn't any documentation on the website, and I've tried reading the source code but can't make head or tale of it. There are the same number of lines in the text block as there are tracks. I've tried with 1- and 2-digit track numbers. I've tried with and without a trailing newline. Does anyone have any experience with this application and this feature?
