https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=27590 --- Comment #1 from Katrin Fischer <katrin.fischer@bsz-bw.de> --- Usually this is a configuration issue. The LDR contains a position declaring the encoding of the record. If that is missing, things will go terribly wrong, like you describe. It's LDR Pos. 9 - it needs to be set to a. https://www.loc.gov/marc/bibliographic/bdleader.html Maybe the default value in the framework doesn't work quite right. Please note: Fields that are deleted from the framework will be lost in records imported from external sources once they are saved for the first time. Koha will delete all fields/subfields not declared in the framework. For this reason it can make sense to only hide, not remove, the fields unneded. -- You are receiving this mail because: You are the assignee for the bug. You are watching all bug changes.
