This reproduces also in my environment.

As we use `pandas` index under the hood, I thought it was pandas' issue.
But I confirmed that this works with pandas
```python
import xarray as xr
ds = xr.open_dataset('test.nc')
se = ds['wdir'].to_series()
se.loc[se.index[0]]  # works
se.loc[se.index[1]]  # also works
```

It looks our issue.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,298839307
