window dimension marker changes on its own

[cremsberg]

Has anyone else had this problem? In one project, I have set up window dimension markers on the floor plan the way I like them using "Window Marker 10". Later when I reopen this project file, some of the window markers have reverted on their own to "Basic Window-Door Marker". This is only happening with one project and it is most frustrating. It is happening to doors too, but not to ALL windows and doors. I am using AC11 windows in a composite wall. It is a very small project file and I am using simple windows.
