AWS Glue Visual ETL misconfigured after leaving the editor

I have multiple Visual ETL configured correctly, but if go back to the previous screen and then try to see the job again, the display editor will lost the configuration and it will highlight some nodes as invalid. I need to configure everything again (schema) in order to work again with the Visual ETL. If I run the job from Workflow it runs successfully.

How can I avoid nodes misconfiguration when navigating away from the visual tool? The job is saved correctly.
