Do you have BrowseTracker enabled ?
Thanks for your help. Yes, I have BrowseTracker enabled.
If yes, is it configured to use Bookmarks instead of BrowseMarks ?
It is configured as "BrowseMarks".
If yes, try to delete it via "ContextMenu -> BrowseTracker -> Clear BrowseMark".
It seems this symbol can't be cleared by "clear browseMark", See the screen shot below, BrowseMarks were "three points like" symbols, I believe it is a "bookmark" symbol.
If it's gone now, it's an interference between BrowseTracker using BookMarks as symbols and the Bookmarks used by the cbEditor.
So, it is still there.
For another test, things become more confusing.
I add two browsemarks before bookmark(screen shot 1)and close my project, but after reopened it, another bookmark appeared at the same position of the second browsemark(screen shot 2).
