It’s very common to find this warning in the status report page of a Drupal site, this happens usually on the development phase while we are adding/removing fields and modules.
As it says in the module doc
This command is a drop-in replacement of the legacy
drush entity-updatescore commands, however
drush updb --entity-updatesis no longer supported. Just run the
drush entupcommand as before.
Just enable the module and run drush entup to fix these fields issues.
