The shelf fetch only makes changes to books that are currently on shelves. It gets the list of books that are on shelves on the device and updates the column in the library with those values. You should probably clear the column from all books before doing the getting the shelf list.

Exactly what you should do depends on what you are actually doing. The get collections function was not really intended for frequent use. The main use case was to get the collections from the device after some sort of disaster in the calibre library. When that happened, the user could get the collections from the device and use that to update the columns that they use to do the collection management. Then they would turn on the collection management and continue from there.
