issue #757 is due to the current update of pandas function df.sum(level=1) which should be replaced by df.groupby(level=1).sum(). I noticed that this bug has alright been fixed in the v0.62 release, however only two of three these problems were found. This PR solves the third.
I hope the PR can be merged soon.
