Nook DRM removal Issues

[seanshuai06]

I either have been having issues with DRM removal from the Nook Windows app to calibre. I have set DeDRM to get the key from the NOOK windows app. However, when I import the book over and try to open it with the reader, I get the This is DRM protected pop-up. I have run calibre in debug and got the below script. It is a manga so unsure if that plays a role in why it will not open.

Looks like the DRM is mostly removed. The problem is

Nook comics and mangas can be non-standard epubs which don't work outside Nook apps anyway. If the entire book is full page scans, you can probably pull out the images and make a cbz file which could be converted into other formats if needed.
