Note that comparison of pandas.MultiIndex instances ignores the names. This may be the cause of the issue.

```python import pandas as pd

a = pd.MultiIndex.from_tuples([(0, 0)], names=["x", "y"]) b = pd.MultiIndex.from_tuples([(0, 0)], names=["not-x", "not-y"])

print(a == b) print(a.names == b.names) ```

Output: [ True] False
