Missing objects

[Dontknow]

When I go to the 'Library Manager' I've got a missing object.
It's a 'Story Marker 17+ (4)' from an unknown library.
Anyone any idea what this could be?

The missing object is the storey level marker selected in the settings of sections / elevations, simply change the storey marker to the equivalent marker in AC18 and this will no longer report as missing
