Aircraft models dissapearing

[edgy glen]

I recently noticed my models for aircraft such as Mig-41 Fb-22D and F111-Ardvark have all dissapeared. The units themselves are still there but are invisible on the map. If I open up their unit details screen there is no image either just a blank space. Is there a way to fix this? screenshot included

This is supreme ruler ultimate 2020 by the way
