[Koha] Curious behaviour with batch modified records - ghost fields

[Jonathan Druart]

Hello Elaine,

Is 245$h linked with a koha field?
Did you keep a version of the record before you managed to remove the
"ghost" field? If yes, did you try to import it on a fresh install to see
if the behavior is the same?
It would be good to have some steps to recreate the issue :)

Regards,
Jonathan
