I can't see 3d object on the canvas? please help

  • I just update my iOS from Capitan to Sierra a few days ago.
    There's a huge bug in clipstudio that the cursor keep clicking on the window behind the canvas. I googled it and ppl told I should re-install and the problem will be gone.
    I did and the bug disappeared, and new problem happen instead.
    Now I can see the 3d object on the right panel but then I drag it to the canvas, there's a layer on layer panel but no object to see on canvas. This happen just with the 3d object but other 3d poses and 3d characters are fine.

    Is there anybody have same problem? any suggest?
