No isbn field in metadata

omp 3.1.2.4 successfully upgrade to 3.2.1.3

no error, but the isbn field is not int the metadata… ive search through the forum no topic same as me…
in the publication>metada no isbn field.
ive activate all metadata in workflow>submission>metadata

my old submission before the upgrade the isbn went into the type field with code like this

Identifier=“xxx-xxx-xxxx-xx-x” [ISBN]

can guide me how to solve this. tqvm

my bad its in publication format and edit the metadata in it… i thought it was on the outside…
tqvm
