Bug: Block glitch - visible only when selected

Hi. I am facing following issue: Two blocks defined in Rhino (brick S and brick M). Both blocks are specifically distributed using Grasshopper script and baked using Content Cache. I grouped baked blocks into larger groups (stripes). Suddenly, all stripes disappeared (in rendered preview) or look like wireframe (although it’s in shaded mode). They only appear when I select them.
