Schema Compare — l10n_status: not in database

Hello,
I run Drupal 7.54 (Linux-Debian 8) with loads of additional modules installed, default language German. Most of my stuff is also translated into English. When running the Schema Compare report, it reports a number of discrepancies between the definitions in the schema (install.php) and tables in the MySQL drupal database. Among them is module locale, where I get the message mentioned in the Subject, concerning table locales_target. I wonder how I can correct this situation. Thanks in advance for any hints.
