Win 7 Aud 2.1.1 repair

I am trying to use the repair function in audacity and I have selected a section to zoom into. It seems it’s not good enough to repair. What do I need to do?

What kind of a defect is is? You can’t repair everything… In fact, MOST audio defects can’t be repaired.

Are you sure you found the defect visually? Short duration defects can be difficult to find, and sometimes you find and repair the wrong defect… Maybe you’ve found a nearby spot where the waveform looks bad but that’s not the defect you’re hearing?
