Can someone explain to me what is going on? I'm going to customer 123 https://ACCOUNT.app.netsuite.com/app/common/entity/custjob.nl?id=123 And when i go to customer 456 it links me to 123 https://ACCOUNT.app.netsuite.com/app/common/entity/custjob.nl?id=456

Can you explain a bit more? Maybe add a screenshot. In your link, there's already a parameter id of the customer's ID 456. It should refer based on the customer's ID
