The question about cellphoneDB's visualization

[MoodyBlues319]

When I use ov.pl.cpdb_interacting_heatmap(adata=adata,
celltype_key='major_celltype',
means=cpdb_results['means'],
pvalues=cpdb_results['pvalues'],
source_cells=['1','2','3'],
target_cells=['Macrophages','Epithelial cell','CD8+ T cells','Treg','NK','DC'],
plot_secret=True,
min_means=3,
nodecolor_dict=None,
ax=None,
figsize=(8,20),
fontsize=10)
The source part of the cell arrangement is disordered, can not be adjusted, how to solve？
