In the https://folio-snapshot-stable.aws.indexdata.com/marcca (MARCcat -mod-marccat-2.3.0-SNAPSHOT.363) some actions still aren't active:
Move field(s) up
Move field(s) down
Sort by field tag number
The action "Duplicate field(s)" doesn't work well. It has problem when you duplicate tag 245 or tag 040 (because are the first tag present at the beginning of the record).
The action related to Move field(s) up and Move field(s) down, probably needs to be re-thinking, because it's not possible to develop them with the component and tecnology available.
The same for action: Sort by field tag number. I will open other feature for each one of this action.
