this all passes. what exactly is the issue? |
Sorry, I should have structured the asserts differently and offered more of an explanation. If everything was working correctly, none of assert statements should have passed (is there an 'assert not equals', or wrap The example code above should result in four unique output DataFrames, one for each I have edited the comments and structure of the example code to be (hopefully) a little clearer. |
Converting to standard form, e.g straight merges. These looks ok to me. So its possible that the aligning logic for frame/series is off. Want to dig in?

how
should not change with a MultiIndex. I know that #6363 is what was actually merged, so please correct me if my understanding is wrong.INSTALLED VERSIONS
