First four landscape tools are not accessible in VR Editor Mode

Tested in Oculus.  Found in 4.18.2 CL 3794801, 4.17.2 CL 3658906.  Not able to reproduce in 4.19 Main due to a crash upon launching VR Mode.  

Users are able to select any of the first four sculpt modes before launching VR Mode and use them within the VR Editor but are not able to scroll and select any mode that is listed before Erosion in the drop down while in VR Mode.

1. Create new, blank project
2. Create new landscape in any level
3. Launch VR Mode
4. While in VR Mode: Select Tools, then Landscape to navigate to Landscape tools
5. In Sculpt Mode, under Landscape Editor, select erosion
6. Notice that the first four sculpt modes (Sculpt, Smooth, Flatten, and Ramp)  are not visible or accessible

Expected: User is able to scroll up and select any of the first four sculpt modes in the sculpt tools drop down. (Sculpt, Smooth, Flatten and Ramp)

Result: User is not able to scroll up to select any of the first four sculpt modes in the sculpt tools drop down
