You need to do two things:

1. Change the "default" in the custom column definition from 0.0 to 3.0. This sets the default for any new books.
2. For existing books you need to set it manually. This isn't hard. Steps:
   1. Search for all books with an undefined GR value. I don't know what lookup name you chose. If you chose #gr then in the search bar enter #gr:false.
   2. Select all the books the search finds. Ctrl-A works on windows.
   3. Type E for bulk metadata edit.
   4. Select the Custom metadata tab
   5. Enter 3.0 in the GR box
   6. Press Apply
