Terrain Opacity/Brush Size Hotkeys stop working after importing Terrain Tools Package.

I created a new project, and painted some terrain. The terrain hotkeys for changing brush size and opacity worked correctly as intended. (Though there is still no hotkey for changing which terrain-layer you are painting, which is quite baffling)

After importing the terrain tools package to gain access to erosion and other tools, the hotkeys do not work for the existing tools, as well as the newly-introduced tools. In addition the new UI for the tools is much more complex and somewhat confusing, even for simple tools such as paint height or smooth height.

It would be great if we were able to use the new package tools without breaking our existing workflows. Hopefully the hotkey support can be fixed up.
