These typos can be seen with this strategy (tested in non-Big Picture Mode on a Windows 11 PC):
1. Select a title that has Steam Input support from your Steam library.
2. Click the controller settings button.
3. Enable Steam Input for the title, if it isn't already enabled.
4. Go to Edit Layout->Joysticks->Right Joystick Behavior. Click the Gear icon.
5. Typo 1: In the Dead Zones section, there is an inconsistent usage of two spellings: "Dead Zone" and "Deadzone".
6. Still in this menu, set the "Deadzone Source" to Custom.
7. Click the dropdown next to "Dead Zone Shape".
8. Typo 2: for the "Cross" description: instead of, "[...] where holding primarily in a single direction for a less that 100% perfect alignment", it should be "[...] where holding primarily in a single direction for a *less-than* 100% perfect alignment" (emphasis added to indicate typo location).
