Providing detailed assistance with DRM removal is not allowed here on MobileRead. Luckily those logs show no problem with DRM removal in your case.
From the logs I can determine that the book you are trying to import is
Exopolitics: Political Implications Of The Extraterrestrial Presence by Michael E. Salla.
I took a look at that book and from what I can see it appears that the publisher screwed it up badly. It looks to me to be based on conversion from an OCR of a scan of a print copy of the book to reflowable format, performed very badly. You are going to find it difficult to work with that book in calibre.
