Short description of error
In the "Object Context Menu", it's titled "Smooth Shading / Flat Shading" but in the "Object Menu" at the top of the viewport, the same options are titled "Shade Smooth / Shade Flat". They should be titled the same as it's the same operation.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
