There is a different spelling with the pack. Just rename the folder and name in the js file to " Anna Belle ".
I had a problem with the packs at first also. The files need to be extracted into the "packs " folder instead of "mods" folder. Then do the step described above. No need to edit the HTML file.
I figured the issue.
Archive called - Anna Belle
Folder inside called - Anna Bell
Actions.js in this folder linked to - Anna Bell
packs.js in the game-packs folder linked to - Anna Belle.
Thus it wont work out of the box. And we need to decide what to edit.
I've edited packs.js because she is Anna Bell.
