[Koha-devel] Duplicate records remain after being unstaged, cleaned

Hello! I added book records (all original records), then when I imported some copy 2s, I noticed errors. I reversed the import but the duplicate records remained. They were supposed to be copy 2s, etc. but now they are in the catalog as multiple records. I did reverse the record import but the records have remained. When I try to manually delete them it says the record does not exist .. yet it shows up in the catalog... any ideas how to delete these records? Any help would be great. David
