Magento 2.4.2 Order Status stuck on processing

When an order comes in an invoice is created automatically and gets send out. I can also find that invoice when i click on the order. If I ship the order then, the shipment email goes out to the costumer but the process is still on processing in the order overview but not in the order itself. If i go on shipments then there is also no shipment shown. The same problem comes up with a credit memo.
