Using Folders to import a group of tracks (as a folder track preset) but then want to delete the un-needed folder

Forgive me - I'm super new to this - I'm sure this is easy

I do a lot of music composing and programming for film and tv and am using track presets to replace the process of importing session data from a template.

In this case I have 2 Bell tracks - one close and one room. I made a folder and put them into it (without routing them to the folder) So with a button, I can import the preset and I get 3 tracks - the folder - and 2 bell tracks. The Folder is selected by defalt and I want to delete it. I added "delete selected folder" and did a UI click to press "keep" so just the folder is deleted.

But I just can't get the folder track to delete.

I Get this error:

Here is my code:

const newTracksWin = sf.ui.proTools.windows.whoseTitle.is('New Tracks').first;

sf.ui.proTools.appActivateMainWindow();

sf.ui.proTools.menuClick({ menuPath: ["Track", "New..."] });

newTracksWin.elementWaitFor();

// Change path here
newTracksWin.popupButtons.allItems[1].popupMenuSelect({
menuPath: ["Track Presets", "Avid", "KS",],
});
// And here
newTracksWin.popupButtons.first.popupMenuSelect({
menuPath: ["BELLS"],
});

newTracksWin.buttons.whoseTitle.is('Create').first.elementClick();

newTracksWin.elementWaitFor({ waitType: "Disappear" });

sf.ui.proTools.trackDelete();

sf.ui.proTools.confirmationDialog.buttons.whoseTitle.is('Keep').first.elementClick();

Many thanks and this program is going to change my life - seriously
