As a general rule we try not to use mirrored parts because they usually don't work as expected. I used them to avoid creating extra work, but now I have a "mirrored default" configuration in each of my two parts as well as the assembly. How do I undo this? I would prefer these extra configs are not in my parts.
Thanks,
Michael
Delete the configuration (rmb on the name and select delete). Go back to the feature tree and delete features that were used only by the deleted configuration.
