Sometimes, during the placement or configuration, it is possible that an item incurs an error and shows up as pink in the plan. Like the example below:
When selected a tooltip will inform you that this has happened.
Now when you right click on the item you will have the option to automatically Attempt to repair the item or, you can Delete the item and re-add it from the catalog.
From version 14.9 you will see the option to repair all cloud items at the same time. This enhancement will fix all of the affected cloud items in one action.
