Hello yes the steps indeed helped. In troubleshooting mode using default theme the issue didn’t happen. After an update to my current theme the issue is resolved.
We’re facing the same issue (I believe it is tracked in https://github.com/Automattic/sensei/issues/4703), and apart from that we also see that the course structure also gets disturbed due to this. Modules get duplicated due to name change, and lessons come out of modules in a course. Would love an ETA on this.
