Inccorect "prefixes" added to titles. Trolls or Bots?

[Sherry]

I have noticed two examples (maybe there are more?) where extraneous and incorrect prefixes are added to book titles.

Not sure why this is happening.

The title of the book is still there (The last part of the title).

I have seen this for "Hidden Camera Detectors..." "Anti Grinding...". Maybe there are more?
In all cases, the first part should be deleted.

Anti Grinding Mouth Guard for Clenching Teeth at Night, Dental Night Guards for Sleep, Nighttime Protection for Teeth with 12 Cleaning Tablets Para Sir Phillip, Com Amor

If it's spam, it's happening on the Amazon end (and then imported to Goodreads by bots). I'd report it to Support: https://www.goodreads.com/about/conta...
