Some nodes states were invalid

Hi everybody I have a problem when loading a Knime workflow, the node are saved and executed without a problem but when I load the workflow again a message appear saying "Some nodes states were invalid" and some of the nodes are now not executed. 

I am attaching a link of the image:

Thank you



Hi mau,

This should usually not happen. I could only say this with certainty after looking into your logs, but from what it sounds like, I would guess that this happens because the content of your metanodes is loaded with some delay. Since it is not directly available when loading, the node state can not be loaded as executed.

Are you able to execute the workflow normally after loading it?
