Mecanim Per-Muscle Settings exact values missing

It's been about 10-15 days since I've had a need to edit the Per-Muscle Settings for a Mecanim avatar and two Unity updates have taken places: 4.1.4 and 4.1.5. It appears the exact value input boxes from the Per-Muscle Settings tab in Mecanim have been removed and only the sliders remain. This is not ideal for my workflow. I've looked for a setting to turn them back on to no avail. I updated to 4.1.5 after I did not see the boxes in 4.1.4. No change. This was not an issue in 4.1.3. Can anyone confirm this or point me towards a solution? I will try a clean install in the meantime.

Much appreciated.

Edit: I'm using Unity Free fyi.
