What happened?

After running sc.tl.rank_genes_groups, I noticed that in the adata.uns["rank_genes_groups"]dictionary, the ptsand pts_restfields are stored as pandas.DataFrameobjects, while other fields (like names, pvals, logfoldchanges, pvals_adj, scores) are stored as numpy.ndarray.

More importantly, the index order of ptsand pts_restfollows the original adata.var_namesorder, whereas the other fields are ordered by statistical significance (p-value or score). This inconsistency caused confusion in my analysis.
