Suddenly important graphics are vanishing. They were there.
The opacity is set to 1.000000 like everything else. There is a checkmark there so it should be visible.
All the parameters for the graphics that are showing seem the same. So why are some of the graphics there, but invisible?
Can you check the transform parameter?
If scale is not too large or to small, for example.
You can also check the filename in bitmap layer instead of the switch layer
