Found at least 3 of the QtQuick3D components which don't have properly visible names in the components view.

1. Repeater 3D (This is under the Components section).
2. Screen Environment (This is under the Components section. This is missing a "t" at the end of the name!)
3. Cube Map Texture (This is under the "Textures" section. Here, the text "Texture" got invisible at the very bottom.)

These need to be updated.
