Metadata limit check includes elastic subfields

I got a MetadataLimitExceededError, saying that the metadata length exceeded 50, which was not the case.

I found this code snippet in records.py:

check_metadata_length(
            len(
                {
                    *self._es.get_field_mapping(index, "metadata.*"),
                    *[k for k in metadata_values.keys()],
                }
            )
        )

It looks like one field of my metadata is counted multiple times with different versions: description.text, description.exact, description.worldcloud, so the limit is exceeds very quickly.

• Can someone explain why those metadata fields are created?
