There seems to be two layers of difficulty preventing me from doing this:
  1. In the plugin configuration there is no metadata field selection option for either grrating or grvotes (I assume 'Rating' here corresponds to the standard Calibre rating, and not the new grrating custom column?).
To download the grrating and grvotes you need to tick the relevant options in the "other options" section. These get inserted as identifiers for your book, which you can then bind to custom columns (all a bit of a hack to workaround limitations in the calibre metadata download API which has a strict set of known columns only it can populate).

So yes the Rating there is the standard rating column.

Anyone who has read enough of my ranting posts over the years would know I never use or recommend using bulk download metadata. For most users it will just lead to corrupting your library like the sort of issues you are seeing. If the search result is linked to the wrong book you are overwriting your book data and would never know it.

As to whether there is some other way to pull that data selectively rather than going through each book one by one - not that comes to mind. Remember every book has to have the right goodreads identifier assigned before you could perform any sort of bulk activity with any level of confidence. And getting the right goodreads id is itself at the whims of Goodreads search engine results and presenting the wrong book more often than you would like.

All of which is only solvable by going through each book one at a time and making sure your data is correct - so you may as well just get the grrating/grvotes at the same time...
