Error in Drop-down Menu which gets greyed out after first time selection

In KNIME, after executing a node, if I attempt to reconfigure it, the configuration fields become greyed out and are not editable. This issue occurs specifically for nodes with dropdown menus, such as the Conditional Box Plot or Histogram nodes. Despite reinstalling KNIME twice and ensuring that all temporary files were removed, the problem persists. I also tried resetting the nodes, but that did not resolve the issue either. I have tried the versions 3.2, 5.3, 5.0, and the latest version. KNIME on another laptop with the same specifications does not throw this error.

For example, when I create a new workflow and use a CSV Reader node, if there are three fields that need to be transformed from number to string, the node only allows me to update one field. After that, all other options become greyed out and uneditable. This issue is not limited to the CSV Reader node—it also occurs with other nodes like the Regression Learner or Box Plot nodes. Essentially, any node that includes a dropdown menu to select options becomes uneditable after a selection is made. I am looking for a solution to address this problem.

Hello @Nihal_K_P,

I tried reproducing the bug you mention, but I was not able to. Do you have specific workflow that showcases this bug?
