Hi,
Do you have any more info? Are they live nested? Only certain levels, random levels, etc?
Previously it seemed like you could rename a level and Microstation seemed to keep track of if it was displayed or not. Now when you rename a level, Microstation treats it as a new level. If it's a new level, there is a setting to tell what to do with that new level--turn on, turn off, or see the config variable. Could your problem be renaming levels?
