Render issue in drop column operation UI4t.

[himanshudube97]

1. Create a drop operation node - D1.
2. Create another drop operation node - D2.
3. Ensure both nodes have different "columns to drop" selections (to differentiate between them).
4. Click on D1, then click on D2.

Issue: The list of selected columns in the operational form (on the right side) does not update when switching between nodes. After selecting D2, the form still shows the selected columns for D1.

Note: This is purely a rendering issue. Internally, everything is functioning correctly: the correct list is being fetched from the database and stored in the state. However, the UI doesn't reflect the changes properly.
