In Interactive Video a Multiple Choice question cannot be viewed/edited/deleted

An Interactive Video assignment was created in which several interactions (7 texts, 2 Single and 3 Multiple Choice questions) were added to a YouTube video (2:16 min). The display time of the last Multiple Choice question by mistake was set to 2:16 minutes (end of the video). After this, the interaction could not be viewed, edited, or deleted anymore. If the cursor is hovered over the bullet point indicating the interaction, the text box "Multiple Choice" appears (see attached image). However, clicking on the bullet point does not reveal the interaction regardless of Edit or Viewing mode.
