Since I started to use ver 1.3.0, on some CDBs, I have some items that are moved to origin position in the diagram, and some others that have two or more representations.
Do I need to check something in the model?
If you refresh this diagram in Capella 1.2 (before migration), these items appear too? In that case it is normal, you diagram are not up-to-date compared to the semantic model. Through project Explorer, a command “Refresh All Sub Representation” provide a way to update all sub diagrams from semantic model.
Do you detach a viewpoint in Capella 1.3?
Otherwise, can you share the obfuscated model and give more details about the issue (diagram name, items, etc…).
