How do I fix a check map Error (Lighting category)

Hello guys!
I am currently working on a ArchViz-Scene and at he moment Im trying to get the best and most realisticest Lighting Results. So when i pressed the build button, there are like 60 Errors for 60 assets with the information: “invalid draw scale” ( in the Check map category). Every asset in the scene has the same error cause so yeah. It also says the drawscale is 0 (NULL) and I dont know how to increase this Value. I´d be so delighted if you could help me! PS: I dont have problems with the UV overlapping and stuff.
Kind Regards,
Dan aka Grimmzjr.

It sounds like some of your meshes are zero in size.
