Search & Insert actions on drop zone BUG

Hi,

In my workflow, I clicked on the plus and chose an action (Query JSON). Configured the action. And now neither this action or another Query JSON action that was in my workflow are visible on the design surface of my workflow.

The actions are still there in the workflow as can be seen when I test the workflow, but they are not visible at all. I can also choose them from the Actions in use.
