Some errors in the error_log with SnapShot Pro

I'm seeing this couple of errors in my error_log, in those sites there's no wpml activated, why is it trying to backup those tables?

[21-May-2016 02:01:15 UTC] WordPress database error Table 'artomult_newdb.7sd98d_17_icl_languages' doesn't exist for query SELECT code, default_locale FROM 7sd98d_17_icl_languages WHERE code = 'en' made by do_action_ref_array, call_user_func_array, WPMUDEVSnapshot->snapshot_backup_cron_proc, Snapshot_Helper_Logger->log_message, Snapshot_Helper_Utility::show_date_time, date_i18n, apply_filters('date_i18n'), call_user_func_array, wp_maybe_decline_date, get_locale, apply_filters('locale'), call_user_func_array, SitePress->locale, WPML_Locale->locale, WPML_Locale->get_locale
