Layout 2022 displays hidden geometry in Hybrid or Vector render mode

Inspired by @DaveR 's sleepless night gallery postings, I modeled the Handrail Stud and Nut.
When I went into Layout and viewed the SketchUp model with hybrid render, remnants of hidden geometry showed. Vector mode is even worse. They dont appear in Raster mode.
Anyone else see this before and have suggestions on how to avoid it ?
