Beam systems in certain floors and ceiling plans are invisible but show blue dotted lines when hovered over.

[Anonymous]

So some of my projects work fine (only in a select amount of views, ceiling and floor plan, but I think that's just view range settings). But in other projects the beam systems in the roof or anywhere I decide to put them are, as I said invisible but show blue dotted lines when hovered over, It's a bit weird that not all of my projects have this issue, But i'm still pretty new to Revit so any help would be greatly appreciated
