There could be two DataArray's which have reversed dimensions for instance.

You would need to inspect the DataArray's:

```python
da = xr.DataArray([[1,2,3],[4,5,6],[7,8,9]], coords={'a':[1,2,3], 'b':[1,2,3]})
ds = xr.Dataset({'da':da})
ds0 = ds.expand_dims('yomama', axis=0)
print(ds0.dims)
print(ds0.da.dims)
ds1 = ds.expand_dims('yomama', axis=1)
print(ds1.dims)
print(ds1.da.dims)
ds2 = ds.expand_dims('yomama', axis=2)
print(ds2.dims)
print(ds2.da.dims)
```
```python
Frozen({'a': 3, 'b': 3, 'yomama': 1})
('yomama', 'a', 'b')
Frozen({'a': 3, 'b': 3, 'yomama': 1})
('a', 'yomama', 'b')
Frozen({'a': 3, 'b': 3, 'yomama': 1})
('a', 'b', 'yomama')
