Nach update auf 5.5.8 verschiedene Cronjobs funktionieren nicht mehr richtig

Hallo liebe Community.

Hoffe mir kann ein Fachkundiger bei dem folgendem Problem weiterhelfen. Die Suche über der, die, das Google half mir nicht weiter, da ich Leihe bin. Zum Problem. Nach dem update von 5.4.6 auf 5.5.8 funktionieren einige Cronjobs nicht mehr richtig. Die folgende Fehlermeldung erhalte ich aktuell beim Shopware_CronJob_Notification:

A new entity was found through the relationship 'Shopware\Models\Customer\Customer#shop' that was not configured to cascade persist operations for entity: Shopware\Proxies\ __CG__ \Shopware\Models\Shop\Shop@00000000753076310000000028bed7d2. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example @ManyToOne(..,cascade={"persist"}). If you cannot find out which entity causes the problem implement 'Shopware\Models\Shop\Shop#__toString()' to get a clue. in vendor/doctrine/orm/lib/Doctrine/ORM/ORMInvalidArgumentException.php on line 92

Andere Cronjobs funktionieren nur halbwegs. Bei Mahnungserstellung, und Artikelbewertung werden keine Mails versendet. (außer Zahlungserinnerung aber keine 1, 2 oder letzte Mahnung)
