 ### Fixed
 - Fixed sharing button for users who are currently visiting a dataset or annotation which was shared with them. [#6438](https://github.com/scalableminds/webknossos/pull/6438)
+- Fixed the duplicate function for annotations with an editable mapping (a.k.a. supervoxel proofreading) layer. [#6446](https://github.com/scalableminds/webknossos/pull/6446)
 
 ### Removed
