Hello, your recent batch with the tool Quickstatements (1710581543492) added some values to the property skådespelare (P161) from the ČSFD database. However, this database doesn't differentiate between skådespelare (P161) and röstskådespelare (P725) which duplicated the values on items such as Odysseus a hvězdy (Q931721). Now, I've reverted your edits on this item, but do check your edits to see if this hasn't created more work for others and be cautious in the future.
Thanks
