can anyone explain my results? I'm baffled
Yes. Your first reading was 1.032. The second reading was 1.010. That means the beer fermented, as alcohol is lighter that water and so the reading decreases.
The potential alcohol % scale is virtually useless for beer brewers in situations like this- so please ignore that.
At the present time, your ABV is 2.89%. That's a bit low, but so is an original gravity (OG) of 1.032. Perhaps that reading was incorrect? A final reading of 1.010 is appropriate for beer, and seems to be correct.
