A longer time ago I created for publications a number of additional metadata, which have worked fine. But since a few months, the old metadata are correctly shown, but when adding a new publication, I only can see the additional metadata-fields but the values are not visible/available. Furthermore, when I try to update an old publication, I also just see the metadata-fields without any values that can be selected and when saving the changes, all metadata values get dropped.

The values to the metadata fields are still available under settings. I also tried to re-create them, which does not solve the problem. It seems that there is a bug at the interface where new publications could be added or edited.
