Drag and Drop

After users check their options, the retry button eliminates all of the choices and the user is forced to start over.  If the user gets 6 out of 7 correct, he has to retry until he get's all 7 correct.  Is there a setting that allows for the correct choices to stay in the drop zones and the incorrect choices to be removed from the drop zones?

We are using H5P Moodle plugin, version 1.17.2 (2019031301)

Normally, the markup of class 'h5p-question-introduction' contains the text for the question which is presented to the user. We styled this class in a way, that it is very obvious to the user, that the actual question text is located there.
But when you create a question of type "Drag and Drop", then the field 'Title' which is described as a field for metadata, is rendered into the markup of classes 'h5p-question-introduction' and 'h5p-dragquestion-introduction'. Please see screenshots attached.

In drag-and-drop interaction, how do you permit the label to be applied to the wrong drop zone? Mine is only permitting labels to be applied to the correct zones; they won't stick to the wrong drop zone.
