Cones and more won't load in MSFS

I’m currently at EHHV. There were cones up until SU10, and I tried to contact the developer of the airport but he hasn’t replied. The cones are third party though, but I did update them and still. No sign of changes. The same thing is happening to me with the payware airport FASH. Except at FASH the tables, fences and a few other things aren’t loading in. The objects at fash are default MSFS objects so I would also like to fix that too. Does anyone know a fix? I have objects level of detail set to 200 and I’m running most settings at ultra.
