Bug report: toggling "IF Switch" node makes workflow unsaveable.

Dear Knimers,

Consider the following workflow:

It can be executed and saved without a problem. However, when I change the IF Switch node setting from “Top” to “Bottom” and execute…

…the workflow can no longer be saved:

Even after switching back from Bottom to Top and executing the workflow, it still cannot be saved. I can only save when I reset the workflow.

The bug may be related to the Correlation nodes. When I calculate the correlation matrices in R instead of native knime nodes I experience no problems:

FYI I work on Xubuntu 18.04 virtual machine with Knime 4.0.2
