how to repair the features coming out from GeometryValidator_faild port

Hi. I am using GeometryValidator for some buildings as multisolids. All of them has been created together, but after the GeometryValidator, some of them come out from Failed part. I need all the 3D buildings. Can I repair them before the GeometryValidator?

I set the set of issues to Detect to Surfaces and Solids.

Thanks
