That sounds really odd! I’m not immediately able to reproduce this behavior using that log text though. Is it enough that the log contains that text or is the copy operation misbehaving when that text is part of the selection? Are you ending up with an empty clipboard or is “just” that part missing?
What OS are you running, and would it be possible for you to attach a small project containing the log you have difficulty copying? You can either attach the project here or create a case.
