Have you tried going to: Settings>Software>Metadata and Ratings, then unchecking the box-Automatically update album art and metadata. ?
If that fails then you could right click on the album you would like to add the songs that rightfully belong in it to and select "find album info", then search the most relevant content, pick the right result and hopefully solve your problem.
Please rate if helpful :D
